In order to get multiplayer working again as soon as possible, we are releasing a mod that will remove the dependency on a deprecated chat filter service so the game can create lobbies and send chat messages in multiplayer. Special thanks to the two modders -- Jamie Wolf and CWolf -- who helped get the mod creation consistent with what the community expects. And thanks to FireDogForge and Bronzite who helped with testing. The files can be found in the post below:


Installations Instructions (included in the README.txt)

Mods are not enabled by default, so make sure they are:
Start BattleTech​
At the main menu, click on mods in the bottom left corner​
Make sure Mods Enabled is checked​
Close BattleTech​

Extract the zip files into a folder named BtMpFix and move that folder to your mods directory. The location of the mods folder differs with the operating system.
Windows: C:\Users\{user_name}\Documents\My Games\BattleTech\mods​
macOS: : /Users/{user_name}/My Games/BattleTech/mods​
Linux: /home/{user_name}/My Games/BattleTech/mods​
Be sure to replace {user_name} with your actual user name.​
The folder structure should look like this when you're done: {Your Mods Folder}/BtMpFix/{Contents of Mod}
When extracting a zip file, depending on your setup, it can create a containing folder for the newly extracted files. Make sure you DON'T have .../BtMpFix/BtMpFix/{Contents of Mod}​

If you're concerned about a malicious dll, you can verify the SHA1 hash of the file by running the following command in your mods/BtMpFix folder:
On Windows:
Open a command terminal - For Windows: (Windows key-R) cmd.exe​
Navigate to your .../mods/BtMpFix folder​
Execute the following command:​
certutil -hashfile BtMpFix.dll​

On Linux:
Execute the following command in the BtMpFix mod directory:​
sha1sum BtMpFix.dll​

The output of that command should be:
SHA1 hash of BtMpFix.dll:​
be1617a8212e1e2d5c485843de0c165e56078f3c​
CertUtil: -hashfile command completed successfully.​


Troubleshooting/FAQ
The mod isn't showing up.
1. Make sure Mods are enabled. When Mods Enabled is unchecked, no mods are loaded at all.​
2. Double check and make sure the mod has been extracted into the proper folder. See above, for more details.​
3. Sometimes your operating system or browser can protect you from files you download. In Windows, these files can become "blocked". To unblock a file on Windows:​
Right click the file in the File Explorer​
Click properties​
If the file is "Blocked", Near the bottom of the general panel should be an option to "Unblock" the file.​
Do this for the BtMpFix.dll and mod.json files.​
If there isn't an option to unblock the file, this wasn't the problem.​

The mod isn't loading.
Make sure the BattleTech Multiplayer fix is enabled​
Start the game​
Click on mods button in the bottom left​
Make sure Mods Enabled is checked​
Make sure BattleTech Multiplayer Fix is checked​
Restart BattleTech​

I receive the error message:
ComStar connection has been rejected:​
Server failed to respond in time.​

This is a problem that existed before the deprecated chat service started causing problems. It happens off and on.​
Some players tend to have better luck joining a lobby when they disable the Auto Refresh lobbies option, but that might just be a coincidence.​

I can create a lobby, but my friend can't join it.
Make sure your friend also has the BattleTech Multiplayer Fix mod installed and enabled. Without that, they won't be able to join.​
Make sure your friend doesn't have a different set of mods than you do. If either of you has a mod that the other doesn't, then you can't join the same lobby. This is to make sure someone didn't do something like bump their large laser damage up do 10000 in their data files on their computer.​

Some other problem?
In your mods folder, there should be a file named modloader.log that will record information and problems encountered when loaded.​
Upload the contents of that file to a forum post with as much detail as you can provide to the bug support forums:​

The process detailed above is the only way this can be fixed/worked around in the short term. If you are having trouble following that process please detail the problem here, thanks.
 
I understand that you have no devs actively working on BattleTech, but the development was pretty much already done by the modders, and you recommend it as a trusted solution to the issue. I don't know the project, but would it be hard to just somehow merge in the changes from the mod to the official game?

I think it shouldn't take a full MD of a dev's work to just review and merge the changes (whether they just patch the assembly with the mod files or fix the source code).

I should be mostly fine with the solution as a developer myself, but you could help:
- People who aren't tech savvy and applying mods scares them, and even more importantly,
- People who want to try out multiplayer and get discouraged by MP not working in vanilla game (without even checking the forums).

A game released in 2018 is still not super old, and it still sells for $40 (even though I can agree that a better part of its value is in singleplayer).

Either way, the modders community deserves praise for that, and I'm glad that customer support still works, at least :)

Nothing about this post has been helpful for me.

I followed the instructions to a tee and the mod will not show up whatsoever.

I extracted into the proper folders, made sure the permissions were correct, there is nothing blocked. Yet it does not show up in game.

It's beyond frustrating that this is the only workaround for the problem to begin with, but on top of that, it isn't working.

I am running off of Windows 10.

I think you've missed this part, at least by the sounds of it. Can you do this again please?

Start BattleTech
At the main menu, click on mods in the bottom left corner

Close BattleTech

You are correct, it's not alot of work to merge the changes by the mod into the main game code (infact it would probably be easier than it was making the mod itself).

From the understanding I got, it's not that the changes were hard so much that there is significant effort and people required to get a build and get it released to the various platforms (steam, gog, paradox, Xbox live, etc).

It's not inconceivable that a new patch incorporating the fix might happen eventually, but this was the quickest way to get a fix for users.

What exactly isn't working? Does the mod not show, are you getting an error message etc? You need to elaborate if we are to try and help and keep in mind that if the mod isn't showing you should double check step 1 in the guide above as you may not have clicked the button to enable mods.
 
can you please explain how?
Mods are not enabled by default, so make sure they are:
Start BattleTech
At the main menu, click on mods in the bottom left corner
Make sure Mods Enabled is checked
Close BattleTech

It's in the guide in the first post. We're not here for you to abuse, mind your tone or you'll get suspended, easy as that.
 
I strongly recommend listening to TinyWiking on being civil with regards to communication here. Abusive discourse will get you nowhere fast.

I appreciate you reaching out to help. I read the post thoroughly and attempted all troubleshooting, however, as I said nothing seems to work. I have other mods installed.. So yes, they are enabled. The other mods work, but this one simply does not show up.
 
Greetings!

I would love to play Skirmish multiplayer.... like I need to play this really badly.

I have already installed this mod above, yes Mods are enabled, I know the directory folder, and I can see the mod is enabled in the game under mods....

I am still finding there are zero lobbies anywhere. I can host one but I have no way of knowing if anyone is online.

Am I missing something?

I have no way of knowing if this mod works but nobody else in this community exists online in the world, or does this mod not do anything?

Can someone confirm if they are playing multiplayer matches ??
