OpenVPN Not Working

I have been able to use openvpn fine since I signed up but all of a sudden I an getting error saying
2021-05-26 05:32:35 Cipher negotiation is disabled since neither P2MP client nor server mode is enabled

Any Suggestions?

Not really a fix, but 99% of these kind of sudden VPN problems can be solved by redownloading the key from the HTB site. I’d try that before attempting to debug this specific problem.
