I didn't ask whether "it works" (what is "it"?), I asked whether you had the same vanilla checksums...
Anyway, assuming you have the same vanilla checksum as the host, starting from vanilla, you can enable mods one at a time on each side (you and the host), and compare the checksums on both sides each time. When they differ you know which mod is causing trouble.

There are TWO unique checksums you need to check.
The first is the starting checksum from the 'Vanilla' hoi4.exe that the Loader displays:
Loader_1.png
From the thread, it would appear you match each other.
If these two are not the same, you should both verify your game files through Steam and check again.

The second appears after you hit play in the loader:
Hearts of Iron IV Screenshot 2020.10.23 - 11.09.30.93.png
This one reflects all mods and command line options (not sure about DLC's) added by the user, these must also match for MP to happen 'fairly'.
If the second 'runtime' checksums are different you need to check:
1- that command line uses the same options (the -debug command line changes this checksum)
2- that you have the same mods and the same versions of mods. With the new patch & dlc, many mods are being updated also.

Hope this helps.

You should probably turn it off in this case.
When you add '-debug' to the command line, it turns on the in-game console and error tracking, which you don't need to synch checksums.
At first you just want to see if the two checksums can be identical with your system and your friends.

Are both of your computers using windows & Steam?
One of the mods on 'this computer' must be the difference if it works for Vanilla.
Try deleting the 3 mods manually then telling the Launcher to re-load them.

If one of the players is on Windows and another on OSX/Linux there may also be a problem with file names in one of the mods you use. On Windows, "Germany.txt" and "germany.txt" refer to the same file while on Unix-like operating systems they don't.
See this similar sounding thread: https://forum.paradoxplaza.com/forum/threads/ubuntu-has-different-checksums-than-windows.1435136/
yes one is on mac and other is on windows but my mac laptop lets me join. and i have tried uninstalling hoi4 and steam. and redoing mods and verify files
