Socket.IO error: class com.github.nkzawa.engineio.client.EngineIOException

[robertv...@gmail.com]

I am constantly getting these errors:

2015-05-09 05:26:52.727 [ERROR] [o.i.m.i.t.MyOpenHABTransportV2] - Socket.IO error: class com.github.nkzawa.engineio.client.EngineIOException
2015-05-09 05:26:52.731 [INFO ] [.myopenhab.internal.MyOHClient] - Disconnected from my.openHAB service
2015-05-09 05:26:56.723 [INFO ] [.myopenhab.internal.MyOHClient] - Connected to my.openHAB service

What's going on with the my.openHAB service?

[Gert Konemann]

The same error here.

I've been getting that for the last 4 months or so... :-(

Thanks

Hi,

If you see this messages in the log from time to time it is normal. First, the Internet is not ideal, connectivity can break sometimes.

Second, we restart my.openHAB service from time to time for bugfixes and upgrades and those restarts close all socket.io connections.

What those messages mean is that connection to my.openHAB was lost but then restored, so basically, if you see them sometimes it is just normal.

If you see a lot of them in your log then it is a problem though. If you have lots of those errors then I would be glad to diagnose what's happening

in your particular case.

Best regards,

Victor Belov

Hi,

Fred, this looks like an old bundle for me. Can you please download the latest file from my.openhab.org Docs section and place it to addons?

I am also seeing same error pattern.
