recently i have no connection to 3D company premises. but it seems that it only happens to my own company. i checked other companies and i can enter the premises easily
i asked other players and it seems not to be my firewall problem
my company is 天津公交 . it's public
edit: my friends in Germany can enter the 3D premises. but in China it seems to be not available. i can check all the data and operate my company, just can't get in the 3D premises. this happened since Tuesday or Wednesday.
edit again: now it seems like my chinese players can't get in my chinese company, but the other companies are ok
tried with start-admin.bat
the log is from OMSI 2\Busbetrieb-Simulator\UE4\Multiplayer
port.txt in that folder is showing 50158
