Myopenhab Cloud connector not going online

Ata · December 2, 2017, 10:44am

Hi Team,

to allow a usage with an Amazon Echo I wanted to activate the myopencloud connector.

I have followed instructions (installed and activated addon, registered on myopenhab.org with uuid /secret and set the settings in paperui accordingly). After updating settings in PaperUI i see the following entry in events.log

12-02 11:03:47.932 [INFO ] [io.openhabcloud.internal.CloudClient] - Shutting down openHAB Cloud service connection

and in openhab.log

2017-12-01 17:32:08.431 [DEBUG] [io.socket.client.Manager            ] - opening https://myopenhab.org:443/
2017-12-01 17:32:08.453 [DEBUG] [ngineio.client.transports.PollingXHR] - xhr open GET: https://myopenhab.org/socket.io/?EIO=3&transport=polling

some background to my environment:
- I have Openhab 2.1.0 running on a Raspberry / installed via apt
- java version is up-to-date:

java -version
java version "1.8.0_151"  
Java(TM) SE Runtime Environment (build 1.8.0_151-b12)
Java HotSpot(TM) Client VM (build 25.151-b12, mixed mode)

- network connectivity is working

curl https://myopenhab.org

I have set the loglevel for the cloudconnector to debug, but still do not see an error. In myopenhab ith says still offline…

Hi!

I’m facing the same issue.
The only logs I see for the openhab-cloud are:

2018-02-03 21:06:19.708 [INFO ] [io.openhabcloud.internal.CloudClient] - Shutting down openHAB Cloud service connection
2018-02-03 21:07:45.172 [INFO ] [io.openhabcloud.internal.CloudClient] - Disconnected from the openHAB Cloud service (UUID = XXX, base URL = http://localhost:8080)
2018-02-03 21:15:41.476 [WARN ] [okhttp3.OkHttpClient                ] - A connection to https://myopenhab.org/ was leaked. Did you forget to close a response body?

https://home.myopenhab.org/start/index/, however, points me the following:

504 Gateway Time-out
nginx/1.10.0 (Ubuntu)

I removed and then created a new user in myopenhab
I re-created secret and uuid files (removed them and restarted OH)
I’ve restarted the Cloud Connector bundle several times
I double checked that remote access is set properly in the Cloud connector settings
Tried updating openHAB multiple times

All this led me to no progress whatsoever
@digitaldan I’ll be grateful for any advice.

@kubawolanin
Did you fix this at all, if so how? I seem to be having the same issue.

This error when I try to open this link:
https://home.myopenhab.org/start/index

504 Gateway Time-out
nginx/1.10.0 (Ubuntu)

And I also get issues when trying to ‘sync my devices’ with more than 5 items with tags. This is because the same code in the cloud connector is used for both purposes.

I have traced the data flow and I see the following happening.

myopenhab.org sends a request to my server.
My server makes the request as asked using localhost and gets a response back.
The response is then either sent or fails to be sent to myopenhab.org since it is HTTPS I am unsure how I can tap into it to sniff the traffic.

So far I think I have narrowed it down to either a myopenhab.org server issue or the packets never leave my network on the way back to that server. Any ideas? What the puzzling part is that it works for 5 or less items with tags, but any more and it breaks for google home.

EDIT: I have now solved this by decreasing my MTU size in my router. This explains why a small number of items worked as the packet size was smaller than the MTU. To diagnose you can do a ping with a set packet size and see if you get fragmentation and 100% loss…

ping myopenhab.org -f -l 1500

See this link for more info on how to test and set the size…
