Failed to connect to the server (io.netty)

I recently started hosting a Minecraft server on my PC (Windows 10). I port forwarded and everything was working fine; I played with friends for a few days. However, today my router got unplugged while the server was running. No one was on it at the time but I’m fairly certain it was actively running. After I plugged the router back in I saw that I could not connect to the server via my IP and port but local connections work fine. I’ve gone through many youtube videos and made sure my firewall settings didn’t get messed up and that nothing is being blocked but I’m stumped. It was working fine so I don’t know why any of this would suddenly be an issue anyways.
