Weird problem with displaying images on a sitemap

opus · February 15, 2021, 9:42am

I ran into a problem where my production system (running OH3 snapshot#2206) won’t display images stored locally like:

Image url="http://MyProductionServer:8080/static/meteogramm.png"

on the Android App (Release and Beta version).
As reported in my Solved “Can’t display images anymore?” Thread, I had this problem when using BasicUI in a browser, but it got solved by updating to #2206 (not sure anymore if that was the real cause). In the App however the images are not displayed.
Using my TestServer (running #2107 ) the image is displayed in the Release and Beta version.

Any suggestions where I could/should look into? My last ressort would be a complete new setup of OH3 for my production server.

I’ll release a new beta version of the app later with improved logging in for image errors. With that we can try to find the issue.

Thanks!

Take your time, that is not WAF related!

That sounds like the problem I obswrved in the other rhread before, which vanished after the update (when shown in a browser).
I have no clue.

This will be fixed by : Fix sitemap proxy URL provided by Rest API by bigbasec · Pull Request #2203 · openhab/openhab-core · GitHub

Thanks, keeping fingers crossed

bhomeyer · February 16, 2021, 12:58pm

I checked out the android code last night to test this and it worked fine. Only problem is that a change like that would break anything that isn’t running snapshot versions, so probably not a great idea.

opus · February 16, 2021, 1:08pm

Asking me, I would say it can wait.

The questions is who is running the App Beta and openHAB release?

Wouldn’t a correct transition require a new version of the app once the next release is out AND a release note to users for updating both?

bhomeyer · February 16, 2021, 1:25pm

I would assume. My original changes were to fix the basicUI as it was broken for images and video. I didn’t think that it would be a breaking change for the Android (and maybe iOS) app, so my apologies.

Not sure if either app has version checking, but if they do, that’s the way to go I’d guess.

opus · February 16, 2021, 1:38pm

Personally I’m glad it wasn’t me spoiling my system. Observed the problem on BasicUI, got it solved by updating (Thanks) and found the App problem. Knowing the cause ( not me!) Is enough for the moment.

Stay healthy!
