Expected Behavior

Expected to be connected ingame in server.

Actual Behavior

The mojang server's login requests are working perfectly. But the in-game connection sometimes fail depending on the IP address i'm using, and depending on the minecraft server. However, not matter which IP I use or which server I try to connect to, the complete connection is fully working using the Minecraft official client. I tried using a paid proxies or a VPS. I also tried using friends computer which didn't work as well. Nevertheless using a friend wifi worked fine.

Steps to Reproduce the bug

1. Use this proxy : 185.96.83.86 SOCKS5. with username : phugo91 || password : tGvI9g4koQ
2. Connect to the following minecraft server domain: play.hadaria.fr using MCC.
3. Get the error

Use Microsoft login method, Mojang login in legacy and will be disabled soon.

Indeed we are using the Microsoft login method not the Mojang one, any idea ?

Does this happen only on that server or on multiple servers?
