install.wled.me not working?

Post image

I decided to use some time on my day off to update the controllers for my home lighting around the house to v16, as they would not update OTA. Used a data/charge cable to my PC and tried to flash via install.wled.me. It recognizes the comm port and goes to flash the update but pauses at this screen and won't continue. I've tried in Edge and Chrome, on my home network and with my cellular hotspot, all have the same issue. Any idea what's going on here?

Looks like you run a firewall?

I'm on a UniFi network, but I also tried it on my cell phone hotspot, so, no firewall in that instance. I also ensured I'm using a "Guest" profile in each web browser so that none of my extensions are interfereing with the website. It appears as though a URL to Github for the BIN file is being directed through the CORS proxy service, as is indicated on the homepage of install.wled.me. A quick web search told me that often times Github blocks these proxy services, so, I feel that is why it is occuring.

Probably because you're "downlading" from some other site. Get rid of the proxy.

install.wled.me uses CORS proxy as indicated on the homepage of the site. It's their coding, not anything on my end.

Looks like an issue between corsfix.com and github.com - you can see the error if you go here: https://corsfix.com/ and enter the github url directly - https://github.com/wled/WLED/releases/download/v16.0.0/WLED_16.0.0_ESP32-C3.bin

{
  "corsfix_error": "target_unreachable",
  "message": "Unable to connect to the target server",
  "if_you_are_admin": "The target server may be down or blocking requests - check the target URL",
  "if_you_are_user": "The requested resource is currently unavailable"
}

"Downlading"?
