io.netty error, i can't connect to my server

Hello!

So I've been getting this "io.netty.channel.abstractchannel$annotatedconnectexception" error for quite a while. I've found some fixes but they stopped working after a while. Turning off my firewall worked for a few days, deleting the netty file in my Minecraft folder helped me for a day as well but now nothing seems to fix it. My friend can join the server just fine, it's only me experiencing this error and I literally have no idea what to do anymore, so any help would be appreciated!! Thank you so much in advance!

EDIT: We both are playing version 1.15.1, non cracked version.

To fix this error you need to delete your playerdata.

This will delete everything related to your player.

Your server must be offline to do this.

Deleting the playerdata:

• Go to worlds
• Then click on files
• Go to playerdata
• Delete the file with your UUID

How to find my UUID? (cracked)

Hello! So i did this a while back and it was working perfectly. Today I got the io.netty error again and deleting my playerdata doesn't seem to solve my issue anymore. I tried flushing my DNS but yeah, that did not help either.

Does the same error occur on a fresh world?

Nope, but I wouldnt like to delete the current one since we've worked quite hard on it.

I am sure. I double checked it twice and my playerdata is gone, the only one in there is my friend's playerdata.

Are you not even able to join or do you get kicked after some minutes of playing?

Yeap, I cant join at all. Everytime I try to join, it says "Connecting to the server" for like 30 seconds or so and then it shows me the io.netty error.

Please check if you have the same problem on a new world.

New worlds work fine for one occassion. For example I can join once but if I try the next time, it's going to give me the io.netty error. Plus I wouldnt really like to leave my current world behind as we have worked a lot on it.
