Similar. I cannot send https request for serveral days through simulator.

Also I tried starting my server app locally and turned off the https requirements. Nothing helped.

MacOS 12.6

After months of living with, I finally found the issue after analyzing the http traffic. It was following entry in properties-section of resource:

Error 500: <property id="pxyz" type="string">xyz + "xyz"</property>

This led to faulty http request. After deleting the quotation marks it was working

No Error: <property id="pxyz" type="string">xyz + xyz</property>

Double quotation marks are also not working ""xyz""</property ...

Intention was to have text with quotation marks as default. This error only occures in App Settings Editor (not on real devices). Maybe this helps others.

Report it as bug because there is no escaping of data in request (and no https).

I ran into this same problem today, and was pulling my hair out trying to resolve it! My settings had been working, I added some new properties and settings, and started getting the "Unable to contact server error". I reverted the settings.xml file, but the problem remained.

The issue ended up being that I had written a String property that had some embedded newline characters in it. (The setting for that property no longer existed, but the simulator still failed to load the Settings Editor.)

Once I changed my code to *not* write any newlines in property values, everything worked again.
