OpenVPN - HMAC authentication failed

[xiaotuzi]

Hi

I'm on 17.1.8 and have had a OpenVPN server running for about a year, however one of the certificates expired so it stopped working. I have then tried to create new certificates for the user and the server but when I export and try to connect from my phone I keep getting the error that:

Authenticate/Decrypt packet error: packet HMAC authentication failed



What could be wrong - I have then created new server, new user, new certificates but nothing helps.
I am exporting the package for OpenVPN connect for android.

I googled a bit but didn't seem to help me.

Any help much appreciated.
