Disconnected when changing region, how to analyze issue?

Hello,

since I moved in RL and have a new internet connection I lose connection to SL EACH time when I change regions, never had this issue before. The same thing happens with a different PC on the same connection, too.

I am pretty sure it has something to do with the new broadband connection, it's from a hotel, I have my own bandwidth available and the admin says all ports are open. Every other application works fine.

Can anyone tell me what I could do to for testing and analyze the problem (testing connection to a specific server or so etc)? I'd really love to hunt down the cause here and try to fix it.

For now I changed the custom port but that didn't make a difference.

Using Second Life 1.22.11 (113941)

update: just tested in combination with a VPN connection over the same internet access and it works. Sadly, I can't keep using the VPN, any suggestions?

I think timing might be your problem. Myself and everyone I speak to has been getting logged out immediatly after a region change TP for the last 24 hours :/
