Cannot join any server with aternos

Hello Everyone!

I am unable to join my aternos server... My friends play with me but they all have cracked tlauncher accounts. They are able to join the server but whenever I try to join, this shows up(The attachment). Only I have a premium account. I tried hosting a premium server but I was not able to join that aswell. Pls help

I can also join Hypixel and other public servers but None of the aternos servers seem to connect. I tried disabling the firewall like i saw online but it didn't change anything

I did it but nothing changed. I even tried changing the server ip but still nothing..(Sorry for the late reply)

No but my friends do.. I have an official account from mojang

I cannot use a tlauncher account as I have all my stuff in my ender chest and I won't be able to get it if I use tlauncher
