Anim notify not triggering when running on dedicated server

Everything worked fine in 4.19 version, but when i switched to 4.20 suddenly anim notifiers stopped triggering on server. It is still triggering properly on client, but server does nothing. Notifier is not at the very end of animation so it gets skipped because of blend. Trigger on Dedicated Server is checked, Montage Tick Type is Branching point. Does anybody have any idea what is going on?

Check that your character mesh set up to always tick
