OpenVPN, convert .der to .crt

I just bought an F2-422 and I'm trying to set up the VPN connection.

I have downloaded the configuration files from the ProtonVPN site and the certificate.

However, the certificate I have is in .der format, not in .crt

As a result, it does not appear in the browser. I googled around, trying to convert a .der certificate to .crt, without much luck.

Eventually, when I try to save a connection, I end up with a spinning icon.

Any ideas on how to set this up?
