TLS Error: TLS handshake failed

[ghost]

Hello

I used your tutorial on configuring a vpn and it was working fine until recently.
Checking the logs on portainer gives the above error. There is more but I am unsure if anything is sensitive or not.
I have tried to restart the container as well as reinstall it but to no avail.
I am using a paid protonVPN vpn config file.
Any help would be greatly appreciated.
Thanks!
