Same here, mine has not been working the last few days, here's the error in the Home Assistant log:

@astrosteve0 are you on last version (1.3.3)?

[astrosteve0]

When the problem first happened, I noticed there was an update in HACS, and I updated it. Currently HACS is not showing any new updates, and I am on version 1.3.2 according to HACS. In Home Assistant itself, it says I am running version 1.3.1. That seems weird. I tried restarting HA, and now HACS shows the 1.3.3 update, I loaded that. I restarted again, and the issue is now fixed. Although in HA, it still shows it running version 1.3.1:

Hello @mrk-its, have you an idea / solution for my problem?

[mrk-its]

1. The mqtt host is blitzortung.ha.sed.pl, can you ping it?
2. mqtt port is 1883, can you connect to it? on linux you can do:

   $ nc -v blitzortung.ha.sed.pl 1883
   Connection to blitzortung.ha.sed.pl (35.158.104.63) 1883 port [tcp/*] succeeded!

3. Try to restart HA, maybe it will be able to reconnect

For now there are over 7k users connected, I also can reconnect without any problems, so it must be something on your end.

Hello @mrk-its, thanks for your hint's. Is only the port 1883 necessary? Seems that my firewall blocks the communication

[mrk-its]

Yes, port 1883 should be enough
