The server mod seems to have a different version of the mod, as it does not have the "mymod:main" network channel, that the client expects to be there.

Connection compatibility actually does not depend on mods and their versions at all. What matters is network channels and registry entries.

Ok, I delete mod on client side and download mod from server and put them on client and still not work.

I check forge version. vesion is same.

Just now, diesieben07 said:

I just noticed it... Your network channel is created in a static initializer of a class with @EventBusSubscriber(Dist.CLIENT). Because you probably don't reference this class from elsewhere, it is not even loaded on the server, and hence your network channels is not registered there.

You should not be relying on static initializers to register things, do it in the proper events.

Oh. Thanks

Forge 1.20.1 OpenAL 40963 and 40961 in DynamicSoundFilters

I copied the mod from Fabric to Forge, but errors 40963 and 40961 appear, I still don’t know the reason, I tried it in a single world, it doesn’t reproduce, the reason for the error is unknown, sometimes it exists and sometimes it doesn’t. andre111/dynamicsoundfilters: GitHub repository
The ported code to Forge is no different from the original, so you can use the source code for testing. The same error occurred on the Fabric build, mods that were on both builds:
Sodium
Create
I only know that the error occurs along the following path: MixinSoundSystem call onPlay -> FilterManager call updateSoundInstance

My friend keeps getting disconnected from our Forge Server

It is, but that is mainly to set up configs per player, I think. I don't believe it is messing chest inventories. I can try to remove that one tho and see if it fixes anything.
