I use esptool or uPyCraft to burn a firmware that I already have in bin file on my computer. And it works well.
A while ago, (when I was less gifted;) ), I used the uPyCraft function to choose the firmware: that is to say that uPyCarft would download the last updated firmware, and after burn it.
I'm trying to get uPyCraft to work again this way, but it seems to be unable to connect to the internet ?! :
"hope to connect internet and try again."
I have uPyCraft V1.1. I also use uPyCraftV1.0 with the same result

I then checked my windows10 firewall, and my inbound traffic rules are activated.
If you've ever had this problem, or have an idea?
Thanks to the community!
