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.
