This looks more like a problem with your company firewall.
I don’t know any “normal” firewall what gives you already a support ticket ID

Hallo,
check the IP of your VPN client.
Sophos for example uses 10.2.x.y and this range has no access per default ino internal networks.

Hello,
You are right, its our firewall. I didnt recognize that message. So i went to logs and founded reason . Search message is more than 2048 character long and ISP rule stop this action. So I temorary disable this rule and its working. But why is that search string so long?

Thanks
Jan

The normal web interface uses no HTTP post only get and sent’s all needed information inside the URL.
I think this is the reason.
