Solved - OpenVPN server issue

Updated the VPN-client on my android phone today (OpenVPN for Android by Arne Schwabe) Now when i try to connect to the vpn-server on my AX-88u i get the following 2021-10-05 15:28:54 OpenVPN 2.5-icsopenvpn [git:icsopenvpn/v0.7.25-0-g4a9cbd88] arm64-v8a [SSL (OpenSSL)] [LZO] [LZ4] [EPOLL]...

Bottomline, it's likely due to a regression that was fixed in 386.4 and above. I assume you're using something older.

No, I am using 386.5_2 .... on my RT-AX86U router !

Did you perhaps use the old certs prior to 386.4 when you upgraded?

IOW, to get around the problem, you have to regenerate the server files using 386.4 or later, then regenerate the client config file.

Thanks for your answer; I am not sure I understand what you mean ...
I have created the OpenVPN Server via the GUI and then exported the ovpn file to my smartphone/tablet (and if the question is did I do that prior to 386.5_2, the answer is yes but do not remember with what firmware version it was) ; I have regenerated the ovpn file yesterday but same thing.
I will try to reset the OpenVPN Server from the GUI and start the creation process again, as you suggest
Thx,
GS

Indeed, regenerating the server files & client config in 386.5_2 solved the issue.
Thanks !
