Fresh install system. Just create a new VPN connection with NetworkManager PPTP using KDE interface.
My journalctl after trying to connect, what problem it can be?

@RinWate
Welcome! Please try to use code tags around the output you post to make it easier to decipher.

[RinWate]

Oh sorry, ok!

[ricklinux]

Not sure i can help yo with that. I don’t use any vpn. It looks like it needs authentication?

[RinWate]

I also thought so, but I set the authorization data in the connection settings. I came to Endeavor OS from Debian KDE. In Debian, the same problem was due to the fact that I had ufw enabled. In Endeavour OS i don’t have ufw installed

And i thought i have problems with routing, or port forwarding, idk

P.S. My language is not perfect, cause English is not my main language, sorry for that…

In this topic: Failing to connect to windows-based VPN (PPTP/L2TP)

User is fixed that problem, but i can’t figure out how he do this

[ricklinux]

EndeavourOS does have a firewall so you may need to set the settings to allow the vpn access.
