Some routes were not successfully added. The connection may not function correctly

[sv-schneider]

Good day all,

I have the following problem:

When I update the openvpn gui on my clients from 2.5.X to 2.6.X it won't let me connect to a VPN.

It does show that it's connected.(Small PC turns green).

but if you look in the log you get the following error:
Connected will route errors:

ERROR: Some routes were not successfully added. The connection may not function correctly

The OPEN VPN server is also running on the latest version.

Maybe someone can give me a hint?

Many greetings
Sven

Hi.

I can agree, having the same issue.

Updated my server from 2.5.7 to 2.6.6 (2.5.7 is fast compared to 2.6.6).
Tried upgrading my existing environment (2.5.7->2.6.6) AND made a fresh install, directly on 2.6.6. Both won't work stable for me.

Clients connecting fine, receive an IP (10.x.x.x) and can "sometimes" ping a server.

Serverconfig:

As said: clients can connect without problems but can't reach any internal ips.

No errors in log.

Help is really appreciated (rolled back to 2.5.7 which works well and fast [so far]).

Thank you in advance.
Best regards
