I need some help on connecting to my own server

I followed all the steps listed on the docs, the server went on, I set all my mods on it, but when i try to connect to my own server that is hosted on my own pc, I always get the same errors: Failled to connect!, Error code 10061, Error code 10038 and Disconnected: Socked Closed Code 3, is there any way to fix this at this point? I’ve checked the ports on my router, my firewall, even changed keys twice in the keymaster site, but none of those seems to fix it anyway.

I would be grateful if anyone helped me

Your ISP might not support you connecting to your own public IP, which is how you join via the server list. To confirm this you can test your server with this tool: How to check the connectivity of your BeamMP-Server - Server Installation - BeamMP Docs

I tried doing that but nothing happened. What should I do? I dont know almost anything about this stuff, but I still cant play with my friends..

Did it output anything? If so, what?

By reading the server logs, I cant really tell what it outputs..
