Minecraft Forge 1.12.2 Server Jar File

I want to make a server for my custom mod pack but the latest version of forge 1.12.2 breaks some of the mods, causing the entire game to break and is just buggy in general. I see the notice that some old installers don't work, but all I want is the server jar for 1.12.2-14.23.5.2846 so I can run my server. If CurseForge can download the client jar just fine, there's no reason there shouldn't be a server jar that already exists. Even if I'm denied official help due to 1.12.2 no longer being supported, I ask that this thread stays open in case someone with the server jar file finds their way here and decides to help me out.

Since it's a server migration that broke the installers, is there some way I can use anything to redirect it to the new server? Is there a way I can fix the installer myself?
