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

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?

thankyou, this really helped me… not sure why expressvpn stuffs didn’t know about this…
