Apps runs on 2019-IMatch-versions, but not more with newer versions

[sinus]

Hello
At home I work still with IMatch 2019.8.4, simply because my computer there has not AVX, hence new versions does not run.
I have some Apps, specialy two, with what I do "work" at home.
Now I have spottet, at home, these apps works nice, but if I let run them on my main-computer with AVX in my studio and with then newest IMatch, the apps runs, but no images will be load.

I tried to see in the release notes, if something has change, I could not find it.

In my browser here at home it works really fine, the adress is http://127.0.0.1:50519/user/cards/index.html

Is there something obvious, what I do miss? I guess, I have to change something in the apps, but have no clue.

Run your app in the browser and check the console for error messages (<F12>).
Check the Network tab for error messages. If IMWS does not like something, it usually returns descriptive error messages.

Endpoints change occasionally, but breaking changes are extremely rare.
Depending on what you have used in your app or how, you might need to change something. The developer tools in your web browser will tell you what the problem is.

Thanks, Mario, I will check this!
