Not sure but you can always try to navigate to your Documents/Mount&Blade Warband/ open the rgl_config.txt with a text editor and searching for "use_secure_connection ="
and change that to 0 if it is 1.
If that does not help or is already at 0 you can go to your Warband folder /Modules/cRPG/
Open your module.ini with a text editor and somewhere at the top change hide_other_mod_server = 1 to 0.
That will show all other modules again but will most likely not help showing crpg servers you do not see right now.
Sounds like a connection problem i would say, might just go away after a while.
To check in windows do start ---> run ---> and enter: ping 46.4.114.45
if you get timeouts it's something with your connection or the routing to the eu servers.
It could also be a problem with the connection to the taleworlds auth server.
Kinda hard to tell
