[RafelGamer20]

English is not my first language,so sorry for any mistakes

 

some time ago i created a modpack to play with my friends(on aternos), it was all going well, but last week, as I was attempting to enter the server this error ocurred(all of my friends already were on the server), then the next day i could enter the server normally, then the next day i couldnt enter again because of the same thing, ive alread tried ever single thing I found (execpt from rebuild the modpack mod by mod), today i entered the server and played for about an hour then i had to stop to take a shower, as i came back i couldnt enter again, (the game was open the hole time). I have no ideia what to do

things that i tried

*Updating java or deleting and downloading again

*excluding all my minecraft data

*changing my name

*some thing on the prompt that I saw
