Myopenhab cloud connector not working on 4.3.3

I need some help getting Myopenhab cloud connector to work. It was working on my previous installation of 3.4 running on a windows 10 pc. Since windows 10 will not be supported any longer I moved my installation to a windows 11 PC and updated to 4.3.3. Now, I cannot get my cloud connector to work. If I log into myopenhab.org it says I am on-line, but if I try to access my openhab dashboard from the home page I get this message:
openHAB connection error: HttpClient@44f56913{FAILED} is stopped
If I go back to my old PC, the only difference is the URL was https://myopenhab.org; the new instructions say to add :443 at the end. Neither method works.
I am not very familiar with software or coding, and could really use some simple step by step guide on how to fix this. Thanks in advance for your help.

How are you accessing it? Through a browser or one of the phone apps? If a phone app, which one? Have you tried accessing it a different way (for example if accessing it using the Android app is failing, try using a browser)?

Hi Rich,
I have tried my Android app without success. Then I just logged into myopenhab.org using my chrome browser. This is also where I re-entered my UUID & secret in case it had changed from my last set up. It says I am on-line, but from the home page when I try to access my dashboard I get this message. Did not have this issue with my older pc with openHAB 3.

I forgot, I even tried to send a notification from the browser logged into myopenhab.org and the push notification worked, it showed up on my phone.

Now I am even more confused. I have a rule that says to send a notification “water leak detected” if my water valve is turned off when a sensor detects a water leak. I manually turned off my water and immediately got the notification. Which means that my openHAB is communicating with the cloud connector. I still cannot see the dash board on my phone or on the browser.

Which UI? MainUI or BasicUI?

Main UI.
I found a thread that may help me. Fix for Jetty error when running on host with many cores
I will try changing the services/runtime.cfg values and see if it helps.
Thank you for all your help

This is becoming an exercise in frustration. I did manage to add the lines from “Fix for Jetty…” I was able to access my dashboard through myopenhab. However, I could not execute any commands, like turn on or off a light. In addition, my local access is also not allowing me to change anything. Adding those lines has affected my automation. I think I will just go back and restore my setup for now.
