GetSockOpt error

Hello, I'm trying to run a Forge 1.20.1 server. I've set up port forwarding on my router for port 25565 and I've verified the port is open. For some reason I can't connect. The server is online, but when I enter <my IP>:25565 and try to connect, no server info loads and I cannot connect, getting a getsockopt error. Nothing shows in the server console when I try to connect, but my game's console says:

[14:42:34] [Render thread/INFO]:Connecting to <IP>, 25565
[14:42:55] [Server Connector #1/ERROR]:Couldn't connect to server

Not sure what to do. The port is open, I've checked my firewall settings and allowed javaw.exe and minecraft.exe to communicate on my network. I've hosted a server before and had no issues, but I have a new router since then. Again, the port is open, the port forwarding rule is in effect. So it's probably something else. Just not sure what.
