connection with the plc could not be established
Hi, I'm having trouble loading my web hmi in both simulation mode and with a web browser. VBM is loading so I think something in my settings is wrong.
is there a way to disable HTTPS (just for testing?)

I'm not sure what you mean by "disable HTTPS" (sorry). It's possible to disable the eHMI feature from the "System Services" page of the Web-Based Management site. You could also try disabling nginx on the device, although I'm not sure how this will help with testing.
As for the problem with the HMI page - starting with an empty project, can you get even the most basic (empty) HMI page appear in a browser, following something like the tutorial on this page:

Problem Solved.
I made a factory-reset and after that my program is working.
I think a factory-reset is mandatory after you put in a memory expantion card in the controller.
Glad to hear that the problem is solved.
If the memory card hasn't been used before, then a reset should not be necessary after the card is inserted using the procedure described in the manual . If the memory card already had user files on it from another device, then a reset will clear those files, which appears to have helped in this case.
Also, if the firmware on a device is upgraded to version 2022.0.3, and if there was already a project on the device, then the HMI pages in that project might show the behaviour you describe. In that case a Type 1 reset and project reload is necessary to solve the problem.
That problem is solved with the recently released firmware version 2022.0.4.
i got firmware 2021.0.9 on the controller, and the memory card was new, i had installed docker and Node-Red on the controller before i bought a memory-card .
