1.3.2 is not supported on this forum due to its age. Please update to a modern version of Minecraft to receive support.

The mod is broken, trying to access client-only code from common code.

You have a very old coremod installed... mods are almost always only compatible with the Minecraft version they were deigned to run on, so check the versions.

Please read the EAQ or the "Logs" section of my signature and post your debug.log

Read my signature again, this is not something you can just say you'll do later.

McMyAdmin is trying to use Java 11: also you are starting a vanilla server:

Where did you get your mods from?

Please read the EAQ or the "Logs" section of my signature and provide your debug.log

1.12 Forge requires Java 8.

If you don't know the difference between server and client you should only be using a client.

Where did you download Forge from, how are you starting Forge, are we talking about a client or server?

Please provide a debug.log without Optifine installed.

Preferably all of it

Can you put your code onto a repo on GitHub and link it here?

How are you building the mod?

How are you starting the server?

I was referring to your port check utility. Is there something noticeably wrong with the bat server that made you run the checker?

Is the function of the server affected in any way or were you running this utility for kicks?

What does the server say that makes you think this is the case?

1.7.2 is no longer supported on this forum due to its age. Please update to a modern version of Minecraft to receive support.

This is fantastic, Chrome, Windows, and VirusTotal all flag it as a virus: https://www.virustotal.com/en/file/580205d38e8385ed1571f3bd27887f9b12afb9d2cda79074a4dee10f2343310c/analysis/1549833316/

Is this a server or a client? If it's a client, what launcher are you using?

That seems more like a multicraft problem, unless the console and/or debug.log say the server stopped.
