hello

after upgrading without reset from 388.1 to 388.2 the ovpn client stopped working and gives the message :
Error - check configuration! .
i do reset with 388.2 and set it up from scratch same message again and finaly... without doing a reset to 388.2 (same settings) I install 388.1 and ovpnclient works fine.
 
From the changelog:


Code:
- UPDATED: openvpn to 2.6.2.  If your client fails to connect
             then your custom settings must contain settings no
             longer supported by OpenVPN 2.6.  Review the System
             Log, then remove unsupported settings that are
             reported in your log.

Perhaps you had Compression enabled?
 
Compression is set to none
Have you read the system log as I wrote in the Changelog to determine what is causing the issue?

There you go. Remove that option, it`s no longer supported by OpenVPN 2.6, and in fact it hasn`t been doing anything for years since that option was only needed 5+ years ago when people were still using BF-CBC rather than AES-*.

A lot of VPN service providers visibly don't know what the hell they are doing considering they still use that setting in their config files...
 
thank you very much for your answers.
in the .ovpn file i add the symbol ' # ' before the word ' keysize ' and now works
 
however, it strikes me that it is possible for the most expensive provider expressvpn to use outdated standards...
