Every time when Im trying to join to external Minecraft server (Minecraft Bedrock Edition 1.16.201 for IOS) there is an "You need to authentificate to Microsoft services." issue. At first, I tried to turn on and then off the double security parameter in my Microsoft account on Microsoft.com and it helped, but about 20 days later the issue appeared again and this time nothing helped. Can you please give me the instructions how to fix this error?

Version: Minecraft Bedrock Edition 1.16.201 for IOS and earlier

Device: iPad

Tried: +) Log out of my Minecraft account and then log in;

           +) Change Microsoft security parameters;

           +) Download Microsoft Authentificator and sign is.

Please, help me to fix this issue, I can't play on servers at all!
