hey, my server(1.19) has been having this problem for 3 days now,

it's stuck on "pinging" and when I try to connect to it, according to the console, I actually join the game and leave after a while

I have tried:
- restarting router
- flushing DNS
- Google DNS (ipv4 and ipv6)
- with/without VPN
- removing all plugins
I gave up on my server and created a new one to play on and it only worked for 1 day and tomorrow it got the same issue as the older server
sometimes it randomly fixes itself but it's really rare (once a day maybe), it's really frustrating and annoying I hope someone can help me fix it
oh and server is cracked
