Hello! I am still very new to creating servers but today I was trying to make one so that me and my brother could play with mods.
I created a forge server and allowed it to install, I also made a run.bat file though had to delete it afterwards as it stopped working, not sure why. Now the server itself does work, but whenever I try to place a modded block it just seems to vanish
here are my latest logs:

I have about 13 mods that I am using including an NPC mod and the Aether mod. My brother has these installed as well, I have them installed on my main game and in the server folder so I'm not sure why it isn't working

You won't get any support since 1.12.x is not supported any more on this forum you need to use a higher version of minecraft 1.14.x - 1.16.1
Note: If anyone would help you they would need your debug.log log and not this one

Are your mod(s) installed both on the client and server side?

 

Nevermind, just found my answer

Realized the answer was in your original post.

Ah! Wait! Are you running the wrong server jar? You need to run the forge jar file using a command prompt or terminal of sorts, not the minecraft server jar file.

This is a vanilla server. To start a modded server you have to start the forge jar.

I just figured that out with a video, but when I try to launch the forge jar this is what I get

Press any key to continue . . .

and that's after having changed the file name to forgeserver and the run task to forgeserver.jar 
If I keep the same names as default on run.bat I end up with a "click a key to continue" without any other info
the thing just doesn't launch

What version of java do you have?

I'm not sure, I installed it quite a wee while ago. Tbh I haven't touched MC until a few weeks ago when my brother bought it, hence why I wanted to make a server with mods (LAN connection kept timing out or having weird errors)

Downloaded the latest version and now I am getting this:

Invalid maximum heap size: -Xmx4096M
The specified size exceeds the maximum representable size.
Error: Could not create the Java Virtual Machine.

I’m not sure. I think 64? Also I was able to manually open the forge server file this time, though after a few minutes the client crashes without showing any error messages

I'm pretty sure you have java 32 bit. You can check using java -version

And if your game crashed post debug.log.

      The crash points to moonlight lib - try other builds or make a test without this mod and the mods requiring it

      Do you have shaders enabled? There is an issue with the mod simpleclouds - remove this mod or disable shaders, if enabled
