Retrying public (IP) . . ."

CSGO.
When I tried to connect to the server I got "Retrying public (“IP”).
I tried to:
Restart PC.
Restart Router.
To use VPN.
To verify game files.
To write “-clientport 20007” in the launch options.
And these things didn’t help me.
I got a lot of bans (Cooldowns) because of that and I don’t know how to fix it.
This post didn’t help me
