Cannot Access WebGUI over OpenVPN

[nona]

Hello,

I have a Peer-to-Peer tun-style OpenVPN.
I can Ping from OPNsense OpenVPN server to OPNsense OpenVPN client. But i can't connect to WebGUI.
At the Browser the Error: Diese Seite funktioniert nicht 172.28.255.1 hat keine Daten gesendet.
ERR_EMPTY_RESPONSE

I can connect to all clients in the LAN.

At the Firewall rules OPENVPN is
allow any to This Fireall
allow any to lan

In the Log is pass.

Since this is our branch I have to do the maintenance from the outside.
Does this have anyone an idea what I can still look.

Best regards
Norbert

I have found the Problem.

The problem is the Browser.
Google Chrome not work.
IE or Firefox work fine.

Not entirely normal..
My main browser is Chrome as well, and I can access the WebGUI through the OpenVPN tunnel. Maybe try something like clearing the cache / browsing data then reopening Chrome?
