ANSWERED OpenVPN auth error and inconsistently link-mtu

[Jommes 0]

I use Gluetun with AirVPN and OpenVPN for a few days, everythng works great. But i have 2 errors every our:
 

WARN [openvpn] 'auth' is used inconsistently, local='auth [null-digest]', remote='auth SHA512'
WARN [openvpn] 'link-mtu' is used inconsistently, local='link-mtu 1552', remote='link-mtu 1604'

How can i fix these errors in my Gluetun docker?

Hello!

In most cases you can ignore those warnings, caused by years and years old unresolved bugs in OpenVPN 2.4 and 2.5 https://forums.openvpn.net/viewtopic.php?t=29557#p89192
According to our tests, these bugs are fixed both in OpenVPN3-AirVPN and in OpenVPN 2.6, but not in any OpenVPN 2.5.x version.
If the warnings are not caused by the old bugs, then you should see failures in connection or no throughput at all. Since you say that everything works great, most probably you can safely ignore the warnings.

Kind regards

Thanks for the information. I see in my client area that i connect with OpenVPN 2.5.8, so i will ignore the errors.
