Hello there.
I didn't receive any message/notification on why my previous thread has been deleted or disappeared.
Here's a repost.

Since yesterday( 15th November 2019) I am unable to log in to the server.

1)At first, it gets stuck at
Code:
"Success"
then in about 30 seconds gets back to the realm list
2) I choose my realm(Icecrown)
3) Then it gets stuck at
Code:
"Logging in to game server"
and in about 30 seconds goes back to the realm list again

The issue was non-existent prior to 14th of November 2019.
Things I've tried to resolve the issue and did help
1)Using a VPN ,but I don't want this as a permanent solution,because I've red on the forums i'm in danger of getting banned for this.
And there is more latency+I have to get the code from my email every time.
Things I've tried to resolve the issue and didn't help
1) Deleted WTF and Cache folders
2)Restarted router
3)Included all WoW ports in the router settings as whitelisted - just in case.
4)Reinstalled client
5)Called my ISP to change my IP address, they did and said they didn't make any changes in the last 2 days

So, in a nutshell , i'm looking for a way to continue playing here without using a VPN , please help. :)
