Since my Upgrade to OpenHAB 4.1 last year I have a strange problem with my Android app.
When I don’t use my app for a longer period (lets say at least 30 minutes) and want to use it again, it doesn’t load my UI and instead I get this error:
Clicking on Try Again changes the error from “Bad Request” to “The user agent does not support public key credentials.”
Clicking on Reload app gets me a 400 Bad Request with “No required SSL certificate was sent” from Nginx. The same happens with purge caches and refresh.
The solution is to force a shutdown of the app and re-open it. Then all works normal again.
I am using Nginx as a reverse proxy with SSL certificates offloading. All requests are forwarded to the 8080 port of OpenHAB. It seems like in some rare cases OpenHAB Android apps forget to send the SSL certificate which I have configured correctly.
Well, it doesn’t look like the official Android app. Also the app doesn’t contain these strings, e.g. there’s no “Purge Caches and Refresh”. How did you install the app?
That looks like the screen you get when you are just using a browser connection to hit your fqdn that is pointed to nginx. I have seen that before but it was when my wireless shutoff to save power . I have also seen that same behavior if you connection timed out due to connectivity issues going through your router and the android device could not resolve your FQDN till you reloaded the home page and if also if you secured your Nginx with basic auth and the cached creds are not saved in browser I have seen that as well. But as I said only when just using a browser connection not using the android app as was stated earlier.
I’m really sorry (also for the late reply) but this screenshot is really made with the OpenHAB app. And indeed it happens if I do not use the app over a longer period (for example an hour on longer) and the app stays on the background meanwhile.
I do not secure it with basic auth, but with SSL client certificate.
Same thing starts yesterday. I cannot access MainUI via myopenhab.org, web browser/android app. Local version work fine. In openhab.log i found alot of errors about ipv6 and REST access
I have had the same issue since yesterday evening. Locally works ok, paperUI also works ok (locally and remotely), MainUI doesn’t work remotely.
In dev tools in Chrome, when connecting via myopenhab I can see:
{"error":{"message":"Expected closing bracket for IPv6 address at index 14: http://[https://home.myopenhab.org:443]/rest/","http-code":500,"exception":{"class":"java.lang.IllegalArgumentException","message":"Expected closing bracket for IPv6 address at index 14: http://[https://home.myopenhab.org:443]/rest/","localized-message":"Expected closing bracket for IPv6 address at index 14: http://[https://home.myopenhab.org:443]/rest/","cause":"java.net.URISyntaxException"}}}
We have the same issue here. It seems there’s a bug on the cloud server side.
Locally all works fine. Cloud connector works also. OH is shown as online in the cloud, but couldn’t access remotely.
All the known tips doesn’t work, as deinstall cloud connector (remove secret and UIID), clearing the cache. Also all updates are done.
So no idea why it doesn’t work.
