Title: Since 18.7.10 ? OpenVPN client resets with "disabeling NCP mode"
Post by: chemlud on February 20, 2019, 03:31:36 pm

Hi again!

I first noticed this on my 19.1.1/LibreSSL (opnsense-patch 90c0c395 installed) with OpenVPN client for site-to-site doing fine for years.

Repeated resetting the connection (no useful entry in OpenVPN server log) with:

Code: [Select]

openvpn[59431]: disabling NCP mode (--ncp-disable) because not in P2MP client or server mode
...and afterwards trying to reconnect. Ok, I thought, let's have a look in the logs of the second machine I upgraded to 19.1.1 LibreSSL yesterday. And there where the same errors, but starting from December 2018, i.e. where I set up the machine with 18.7.10. So the problems apparently started with 18.7.10.

Any ideas what this could mean, a quick Startpage gave me nothing conclusive (as usual with tunnels and error messages...).

...although we are still on OpenVPN 2.4.6 this might be a hint:

"Please note that LibreSSL is not a supported crypto backend."
