I can't connect to multiple server

[Eunki]

The version is 1.19.2 and the jdk version is 18.
I get these errors when I run the server.

[Forge Version Check/WARN] [ne.mi.fm.VersionChecker/]: Failed to process update information

java.net.http.HttpConnectTimeoutException: HTTP connect timed out 

 

If I try to enter the server address as localhost, I can't connect. The server status is green, so it's open, but I can't connect. 
If I set the online mode to false in the server-properties file, I can connect, but I can't load the skin.

Strangely, when I go into single-player with the forge, it doesn't load my original skin and I look like Steve.
If I connect to vanilla without the forge, the skin looks fine.

If I use the forge version 1.12.2, my skin looks fine when I connect to single player, and I can connect to other multiplayer servers just fine.

I've tried reinstalling Minecraft, Forge, Java, and rebooting my computer.
