[BUG] Many UDP free servers no longer connecting

[autogris]

Currently many of the UDP free servers in Netherlands gives authentication error, forcing the user to try several times until finding a server that works. Maybe the server list must be updated?

To Reproduce
Steps to reproduce the behavior:

1. Run at the terminal "protonvpn c --cc nl -p udp"
2. Connection authentication fails at several servers like NL-FREE#157 for instance
3. Repeating the command eventually finds a working server

Expected behavior
The application should only try to connect to working server.
