Description

I am using Rocket.Chat 2.14.7 on Windows 10. After update server from 0.72.0 to 0.74.0 notifications doesn't work anywhere eg. from web browser (Google Chrome) or from Windows Client 2.14.7 even "Test notification button" in user settings doesn't work.

Before update server to 0.74.0 notifications work well.
