Dedicated Server Editor and Build version

I have create project multiplayer with server host and server dedicated…when I connect client to server host work all well, when connect client server dedicated many function not work well, why? where is different with server host and server dedicated?

When I test the project in the editor, with Dedicated Server enabled, all work perfect but when I build Dedicated Server and launch project there are many function not work well.
Why this different from Editor to Build version?

Can help me?

Do you use a lot of animation notifies? I had a similar problem yesterday with a dedicated server build, and it was because the character mesh was set to only tick pose when rendered. Since the dedicated server never renders anything, no animations notifies were triggered. By changing it to “always tick pose” it all worked.
