Client exception in transport_recv: process_server_push_error: Problem accepting server-pushed peer-id: parse/range issu

[goancea]

Hello all,


I have a Mikrotik router and I am using openvpn server to connect over the Internet.

For the last months all is working fine, but after I upgraded OpenvpnConnect to version 3.3.7(2979) when I am trying to connect to VPN the below error is received:

Code: Select all

[Jun 16, 2023, 11:13:56] Client exception in transport_recv: process_server_push_error: Problem accepting server-pushed peer-id: parse/range issue

Here is the full log:
A.A.A.A = is the public ip address of the router

And the openvpn config file on the client is:

I did not change anything on router, only the client was upgraded to 3.3.7

Thank you

Same here after updating Mikrotik RouterOS to 7.10.
Also stopped working OpenVPN client connections from other Mikrotik.
Passepartout (iOS app) connects but does not route to the VPN netwrok.

I suppose the issue is caused by the Mikrotik update...

Downgrade to 7.9.2 solved the issue

Same issue here with Mikrotik 7.10 and Android.

I hope Mikrotik guys will fix it soon. I don't want to downgrade if it is not a must but good to know downgrade can help.
