Hello Daniel,

I have tried to reproduce already - it works for me. I have a self signed certificate on the App Platform and use myApps launcher.

This must be something else.

A complete console log would be helpful. The info about "Upgrade-Insecure-Requests: 1" is too short. It seems you have WebSocekt connection already? Than it is not an SSL problem.

Best Regards

Andreas Fink
