The GUI is no longer responsive, even though the logs show no errors

[swvajanyatek]

After a restart, the GUI no longer loads via http://machine_name:8112/. The logs don't show any errors, as far as I can tell. How can I troubleshoot this problem?

I am also facing the same issue. I've been debugging using different nord server profiles and timeout configurations to no avail. I wonder if this could be a nordvpn issue?

[binhex]

@swvajanyatek your issue is Auth failure, if you are using nordvpn then there had been a change in Auth, contact your VPN provider for details

[swvajanyatek]

@binhex thank you for confirming the root cause, it wasn't clear that it was an auth problem (and I didn't think that would impact the UI). @ncbrown1 - I found that using my service credentials solved the problem for me - https://my.nordaccount.com/dashboard/nordvpn/manual-configuration/

Thanks a ton @swvajanyatek and @binhex ❤️😊🙏 Switching to Service Credentials solved it for me as well! 🙏

[swvajanyatek]

Sweet! First time I've actually helped someone else solve a real problem!
