Except lifeboat boat i cannot join any server or realms

Whenever I try to join any servers,realms or my friend's world, I am unable to do so. Believe me this is not a technical problem of the internet,if it was I wouldn't be able to join Lifeboat either but I could. This started from 1.20.

It is not just me but 100 thousand of players from India(I saw a vpn tutorial in YouTube to fix this it had a lot of views). I could join servers by using a vpn but it's slow and laggy. 

Please do not flag this as duplicate as no one here has raised this problem in Mcpe.
