After taking to Minecraft Support team for after an entire week, I ended up here
My minecraft server stopped working for no reason, and I cannot join it anymore, and no one can either
It worked for a good hour and then it just stopped, I did not do anything that may have broken it, I was just paying normally.

Here's a list of what I have tried to do to fix it and did not work, also what the Support team told me to do:

-Restarting game
-Restarting computer
-Reinstalling game (clean install with no mods)
-Deleting the server and making another one
-Deleted any third party software that I was using( I was only using optifine and a Shader)
and I do not own nor used MCLeaks, I heard that is the problem in most cases.
-Checked my internet connetion multiple times, I live alone so there is no one else using it, and I use a wired connection ( also my internet is 1gbps so I doubt it isn't enough for a minecraft server)
-Restarted router multiple times
-Changed DNS Server Adresses in the "Network and Internet" setting in windows to 1.1.1.1 and 1.0.0.1
-Checked the Xbox Live Account Settings to see if everything there was set to online
-Logged in/out of the game and launcher

I hope I didn't miss anything I did over this week of trying to fix this issue

Keep in mind that the server worked for an hour, so this confirms me that the port forwardig is done right.

Also, if this helps you, I see some errors in the console when starting the server (I also had them when the server worked) and here is the log I get when starting it :

And I can join the server only when I use "localhost" as password but not when I use my IP adress

Thanks for assistance!
