You need to post your logs/debug.log and do it on a file sharing site.

The log above doesn't even show you connecting to a server.

 

The error says one of your mods has broken networking.

These are usually difficult to track down and normally require you to experiment with removing mods to find the problem mod.

 

But you can try adding the following to your "java arguments" (same place you set the -Xmx memory value)

-Dforge.logging.mojang.level=debug

This will add Mojang's network debug logging to the logs/debug.log

Boilerplate:

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com  You should also read the support forum sticky post.

That's not the debug.log

It also says you can't connect to the server.

[16:29:49] [Server Connector #2/ERROR]: Couldn't connect to server io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no further information: xxxxx

Caused by: java.net.ConnectException: Connection refused: no further information

So either your connection information is incorrect, there is something wrong with your networking or the server is not running.

That's the server debug.log

It doesn't show anybody trying to connect?

It's unlikely to have the network error you originally posted anyway, because that will be on the client.
