Breaking EG4 wifi dongle unable to connect

I have exactly the same issue, but with an additional complication: my solar provider, Sovereign, no longer exists, i can get support here?

I have the same issue, it started around 1/22/25. I believe its something with the cloud server as I can see the inverter on my phone when I'm connected to the Wi-Fi dongle AP. Also nothing has changed with my network setup, I'm running all TPLink devices since before I got this 6000XP. I can also ping the dongle on any computer on my network and get 100% good replies. I have tried every way to reset this dongle and reconnect it. My dongle is a BJ####### S/N unit and I don't have all the advance options some of the recovery guides have. 

I might be having the same issue? In doing an initial set up, I can't get past the message "Connect dongle of device failed" on the app. I can see the dongle Wi-Fi but cannot connect in the Dongle Connect step or by doing a Local Connect. Any help would be appreciated.

Can you both send me a private message with your dongle's serial number and also a screen shot of the Dongle connect Parameters as shown on the image below. 

It would be super helpful if anyone could actually post some background info on this problem. The only helpful comment so far was the original post. 
Example: (from EG4 staff) "here's a summary of the issue and why it requires EG4 support to intervene" or "here's a summary of the issue and here's how you can fix it yourself."

Thank you
