I set up my own server and i noticed every time i joined, i loaded into the world, i could walk around for a about a minute but then it times me out. i can break blocks but the blocks dont drop on the ground, they just vanish, and when i rejoin most blocks reappeared like they never have been mined.
the interesting part is, when my friend joins, all is just fine, he can play smoothly, no lag, he can mine, doesn't get kicked, it only happens when i join. so for some reason i tried using a VPN and then join the server and it worked, i could play, mine and wouldn't get kicked from my own server.
the problem is that i cant use the VPN for reasons and i want to know what is causing my problem and how i can fix this. it has something to do with me being on the same address as my server but i dont understand it.
i hope this is enough information, if you need to know anything else i would love to get back to you since i really wanna fix this.
i use a windows 10 pc as server and a separate windows 10 pc to play.
