"NoConnectionError", even before "connected"

[philipgo]

Problem/Motivation

I hope this is the right place, please correct me if I should post this in https://github.com/zachowj/node-red-contrib-home-assistant-websocket

I stumbled upon the problem that certain nodes show a "no connection at:" error with a time corresponding to a restart of Home Assistant or the Node Red addon.

When looking at the Node Red addon-logs of the restart, I see many connection errors at times even before the addon reports "connected". Should connection attempts not wait until a connection is established? Is this the reason for the "no connection at:" error displayed by some nodes after restart?

Enabling connection delay and heartbeat made no difference.

Expected behavior

See no "no connection at:" errors :)

Actual behavior

see above, logs:
