Just wanted to mention that this is working now. I had email contact with M5stack and they recommended using the webburner. Not sure if that is the reason it works now, but I can program the device wireless from Uiflow2 with no problems. CoreS3 and Uiflow2 seem to work in the Nordic countries now.

This was my first day of developing with the cores3, which is also my first M5Stack product, and I wish I'd found this post right at the beginning and saved myself a huge amount of wasted time.

I assumed I was an idiot and did not know how to use UIFlow 2.0. Turns out it was was a server issue all along. The error messaging needs to be improved so first-timers know if they are doing something wrong or there are server issues.

@ajb2k3 May I politely suggest you relocate your servers somewhere outside the great firewall perhaps? Or run servers in different locations so people have a choice?

@ajb2k3 Thanks for fighting the good fight! With the crazy geopolitics we have these days, relying on a connection to a server in China to program your microcontroller sounds potentially a little too risky for my liking, I'm sure other companies in the West would feel the same.

@iamliubo I'm based on Sweden. Can we get some timeline for when this connectivity issue will be resolved for those of us not fortunate enough to live in China? At the moment the cores3 is a very beautiful looking paperweight on my desk, it has no use at all without UIFlow2.0 working.

@mtylerjr thanks, I will look out for that option in future!
