Openvpn issues - Data channel cipher negotiation failed (no shared cipher)

Off-topic

I am having an issue with my .ovpn credentials, for some reason when I tried connecting this morning using my credentials I am getting the error:

2022-06-29 08:40:44 AUTH: Received control message: AUTH_FAILED,Data channel cipher negotiation failed (no shared cipher)

Is anyone else having this issue, or know of a fix?

Edit your downloaded ovpn file, replace ‘cipher AES-128-CBC’
with ‘data-ciphers-fallback AES-128-CBC’

Thanks for that, this has done the trick. My credentials are not working.

May I ask, what changed causing my previously working .ovpn credentials to no longer work? Was it an update to HTB’s VPN?
