I tried reinstlling byond, I'm currently using my phone mobile hotspot to connect to the internet. Before when I done this I had no problem but after a day later I've been getting a BYOND Central not accessible error. I fully allowed access to byond in windows firewall and I even ran a cmd/run prompt to see if I could fish out the problem {Under the guidance of a previous responders post} but still no luck I even ran the program under adminstration.
