Myopenhab.org Connection to host failed

Hello,

is the myopenhab.org down or is there any problem with the service?
My local OH2 server is running on OpenSuse 15.1, OH server version: 2.5.7, Cloud connector version 2.5.7.

I can see OH2 log entries saying that the instance is connected to the server.
Connected to the openHAB Cloud service (UUID = xxxx, base URL = http://localhost:8080)
But sometimes this message appears:
10:41:30.734 [ERROR] [.io.openhabcloud.internal.CloudClient] - Error connecting to the openHAB Cloud instance: {} io.socket.engineio.client.EngineIOException: xhr poll error at io.socket.engineio.client.Transport.onError(Transport.java:63) [bundleFile:?] at io.socket.engineio.client.transports.PollingXHR.access$100(PollingXHR.java:26) [bundleFile:?] at io.socket.engineio.client.transports.PollingXHR$6$1.run(PollingXHR.java:140) [bundleFile:?] at io.socket.thread.EventThread$2.run(EventThread.java:80) [bundleFile:?] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) [?:1.8.0_252] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) [?:1.8.0_252] at java.lang.Thread.run(Thread.java:748) [?:1.8.0_252] Caused by: java.io.IOException: 400 at io.socket.engineio.client.transports.PollingXHR$Request$1.onResponse(PollingXHR.java:234) ~[?:?] at okhttp3.RealCall$AsyncCall.execute(RealCall.java:141) ~[?:?] at okhttp3.internal.NamedRunnable.run(NamedRunnable.java:32) ~[?:?] ... 3 more

Also the Android application sometimes connects (shows the overview screen), but when I want to open an item detail (submenu) it shows a spinning icon and then says Connection to host failed.
On local network it works perfectly.
Is anyone else experiencing these kind of problems?
Thank you!

Is anyone else experiencing this problem? I can’t use myopenhab.org. I’m still on OH 2.5.11. The instance connects to the server, and I’m trying to use remote access with Android phone. Few minutes it’s OK, works flawlessly, shows the sitemap. Then something happens, and opening a subitem results in error “Connection to host failed”. When I try to connect to dashboard using web browser I get result “504 Gateway Time-out”.
On the local network it still works during this outage. The log doesn’t contain any error yet and myopenhab.org shows “online” status. Then I change something manually (e.g. switch a light on) the local instance wants to send this information server and it realizes the connection is lost (?), then it reconnects:
15:05:14.340 [ERROR] [.io.openhabcloud.internal.CloudClient] - Error connecting to the openHAB Cloud instance {} io.socket.engineio.client.EngineIOException: websocket error
...
15:05:14.353 [INFO ] [.io.openhabcloud.internal.CloudClient] - Disconnected from the openHAB Cloud service (UUID = xxx, base URL = http://localhost:8080)
15:05:15.275 [INFO ] [.io.openhabcloud.internal.CloudClient] - Connected to the openHAB Cloud service (UUID = xxxx, base URL = http://localhost:8080)

After re-connection it works again few seconds/minutes then in happens again and again. I already re-installed the computer, I’m pinging the myopenhab.org server, but it works, so I don’t know what is the problem. My OS is OpenSuse 15.2, x86 (64bit), openjdk 11.0.9, firewall disabled.
