Cant access private server

I run a private server, hosted on my PC. I've been trying to access the server for several hours. It keeps on saying "Connection timed out: no further information" nothing has changed since I accessed the server yesterday. I've tried restarting the server, the launcher, the PC, my VPN, and even resetting the network configuration on my PC. Nothing has worked. I do not know what to do to access the server.
