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
