Common macOS application issues

This article covers known bugs and issues with ProtonVPN application for macOS. If you have faced an unknown error or issue with the Mac VPN application that is not listed here, please contact our support at

Mac VPN Application issues:

General issues with the software:

This does not involve connection issues, but general UI bugs that you might face.
The best thing you can do in this situation is to reset the application to its basic parameters by deleting the application data. You can do so by following these steps:

Open ProtonVPN application-> Find Help on the toolbar while the app is opened->Click on Clear Application Data.
This will delete any information related within ProtonVPN.

ProtonVPN Keychain error.

This error message is received in the login process, after entering wrong credentials several times into the neagent when trying to establish a connection to the VPN server previously.


Possible fixes for this issue :

  • Log out of your Mac user account and log back in.
  • Restart your Mac

Network request timed out.

This error message is displayed when there is something wrong with login services. It could be an issue with your network, or ProtonVPN infrastructure downtime/maintenance.


Simple possible fixes:

  • Restart your mac device and check the application again.
  • Check if you are able to reach our website or ProtonMail website.
  • Check if you can login on other devices.
  • Go to system preferences > network > disable and enable Wifi or simply unplug Ethernet cable from your mac and plug it again.
  • Give it a few minutes and try logging in again.

For advanced troubleshooting:

  • Open terminal and and run ping
  • Run a tracroute – traceroute

If you do get a response from those links, ProtonVPN services are working and there could be something with your network or device.

If you do not get a response from both actions, please contact our support team with this data as well your machine information and ISP.

Are you from restricted network area? For example China, UAE, Turkey, Egypt, Syria, Cuba, Saudi Arabia, Iran and many others.
Or maybe you are using your work network that could have restrictions?

If so, your ISP might be targeting and blocking access to ProtonVPN services and blocked the access to it. In that case try setting up tunneblick connection method which uses OpenVPN.

    this requires 12.2 but my OS X only goes up to 12.1, do you have an older version that will work on my computer?

  2. ProtonVPN Team

    Hello Blake. There seems to be something wrong here. Our software is supported from 10.12 and above. Did you mean 10.12.2? Please contact our customer support team for detailed troubleshooting.

    I am getting an “internal API error” (in red) when opening ProtonVPN for the first time on MacOS High Sierra.
    Am I missing something?

  4. ProtonVPN Team

    Hello, Please restart the mac device and if that does not help please contact our customer support team here and we will do our best to help you out!

    Why it kept on asking for password? When i’m connecting to united states?

  6. ProtonVPN Team

    Hello, please contact our customer support team as we need additional information.

    I have the same dreaded “Keychain error”.
    It seems ridiculous to have to logout and reboot my machine anytime I want to connect to the VPN. If I wanted to do retarded windoze type reboots every time I do something I wouldn’t be using a UNIX based OS. Please fix this issue, it’s obviously not user error, but something within the scope of your vpn application.

  8. ProtonVPN Team

    Hello Henry. Please press CMD+ Space (search bar will appear)> type Keychain Access> press on the lock in the corner (in order to have administrator privileges)> in the same window search bar type- “VPN”.

    Right click and choose Delete all the files related to ProtonVPN, OpenVPN or Tunnelblick. This will delete remembered passwords for connections that you had with our servers.

    After all of this try connecting again, it should prompt you for your credentials, keep in mind that it may also ask for your Mac’s user account info too.

    No joy from here either, I was being asked for OpenVPN Password originally, however don’t believe i have that info. Now i just get Keychain error

  10. ProtonVPN Team

    Hello Garry, the time you install our application and log in with your protonvpn account, you make a connection and then you are asked for keychain password – that is your mac user password that you use to log in to your mac when you wake it up. If you face any issues we would suggest contacting the support

    OSX 10.12.6 app v1.2.3 is not working at all, same issues as js above. Had to dig into the os logs since pv logs don´t show either. Works from windows pc app in the same network. I have restarted the Mac, this is the only active session, etc. Logs seem to include PI so I’m only pasting this bit here:
    11:40:11.527433 -0500 secd ProtonVPN[1040] copy_matching Error Domain=NSOSStatusErrorDomain Code=-50 “query missing class name” (paramErr: error in user parameter list) UserInfo={NSDescription=query missing class name}

  12. ProtonVPN Team

    Hello Osox. This is a quite strange error that we don’t recall if we have seen it. It would be the best if you contacted our tech support via email form for detailed investigation.

    Regarding the “Keychain error” message I can say that it is not occuring in non-root users on macOS X High Sierra (version 10.13.6 Beta (17G39b)) with ProtonVPN on version 1.2.3.
    However, if logged into the root user I will always get this error message. I think it’s due to the right management in macOS but it may be worth including that in the article.

  14. Brian Phillips

    Sent an email to support but having the same problems. I live in China. I have the most up to date software and installed TunnelBlick and the new ProtonVPN software. I am not able to connect with either software, followed all of the instructions from the site

  15. ProtonVPN Team

    Hello Brian, our customer support team will keep you in contact and troubleshoot you further on. 🙂

    I get a sad face over the message “Connecting Failed” and the options [Cancel] and [Try again].
    Running macOS 10.13.5.
    Using ProtonVPN on Win 7 works fine using my ISP, Bredbandsbolaget/Sweden.

  17. ProtonVPN Team

    Hello, please contact our customer support team and we will surely help you out!

    Any chance that this will come to older but still supported versions of macOS (thinking 10.12)? I have some older machines which I can’t upgrade to 10.12 that I still use and would love the convenience of the ProtonVPN app.

  19. ProtonVPN Team

    Hello Chris. Sadly, for now there are no plans to support older macOS versions that are below 10.12. We`ll let our customers know on social media if any changes will come.

  20. Traveler

    I often travel to China, UAE, Qatar, Turkey, … May I use MacOS beta from there or only tunnelblick and securecore ?

  21. ProtonVPN Team

    Hello. Currnetly macOS application will most likely not work due to its used IKEv2 protocol, but it can work, it only depends on ISP most of the times. The best working solution is Tunnelblick as it uses openvpn which is working most of the times in restricted countries.

  22. JS

    I have downloaded the MAC beta client and followed the tutorial to copy it to applications, when i click on it to open it it doesn’t do anything (i get no error messages and i don’t get the logon screen). Eventually i get a message that says that the application has closed unexpectedly. The error report states : Exception Type: EXC_CRASH (Code Signature Invalid), Reason: Namespace CODESIGNING, Code 0x1
    I have tried restarting my MAC and starting again from scratch – i get the same issue. Am I missing something?

  23. ProtonVPN Team

    Hello, May we ask, what application version do you have installed?
    Try using this application which has it fixed, then update to the latest one.

  24. JS

    Hi – i downloaded the client from the protonvpn site at the time that i tried this originally. Unfortunately I didn’t have a chance to try this again until today and your download link has expired. Is the fix that you mention in the beta software generally downloadable from the protonvpn site now?

  25. ProtonVPN Team

    Hello JS, yes, the updated software version is stored on our website and you can download it from here –

  26. JS

    I’ve tried downloading this and following the instructions again. I still cannot get the application to run. It installs and i can double-click on the icon but it does nothing at all until i get an error message that states that the application closed unexpectedly. The log has the same error message as before “Termination Reason: Namespace CODESIGNING, Code 0x1”. Any idea if there is anything else i can try or should i give up?

  27. ProtonVPN Team

    Hello Js, have you tried restarting the mac and performing the installation again? Also, is this the first time installing the ProtonVPN mac application? Please dont hesitate to contact our customer support team here –

  28. CN

    I have tried my correct password for OpenVPN.
    I tried the correct password for ProtonVPN.
    I tried the correct keychain password for my computer.
    I restarted my application. Still nothing.
    I have been at this for over an hour.
    What exactly is keychain password for OpenVPN if it is not the same as the OpenVPN password?

  29. ProtonVPN Team

    May we ask, have you tried restarting your mac?
    When keychain access comes up, you have to enter your Mac User password that you use to log in to your laptop.
    If you still face issues with our application, we recommend contact our support via this form:

    I have the same issue CN has described. I’ve been trying over several days and have ZERO luck. I have no issues using the VPN via Tunnelblick but when trying with ProtonVPN client, none of the keychain passwords work. Like CN, I have used the protonmail password, the previousy used mailbox password, the original password used for tunnelblick and the apple ID. Needless to say, since I have been attempting to get this to work over several days, I have logged out, rebooted, etc. I’ve even uninstalled and reinstalled. Help. (Note: I also updated to MacOS X10.13.6 since my earlier OS was not compatible.)
