Hello, the problem was resolved by itself. Thank you.

In Firefox. Google works...

Hello, help me figure it out, for some reason I stopped connecting to the room. At timeout connection from the client I receive on a server such error.

(node:9386) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: remote room (HJg5nXqUbX) timed out, requesting "locked"
(node:9386) DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

Client console:

colyseus.js: trying to send data while in 0 state

Server debug:
room created: S1xqwOqL-Q
room disposed: S1xqwOqL-Q

Het @endel. This resolve my problem. Thanks you.
