Nodemcu and http update

PostPosted: Tue Aug 21, 2018 8:57 am

Hi all, I'm new here; so if I posted this in the wrong forum, I'm sorry.

I'm trying to setup my ModeMCU to get it's updates from a web server. I set up a PHP file to make sure it doesn't keep downloading the update file. My web site is being hosted by Ipower.com It's not local so I'm have a hard time getting verbose error logs. I do know that I can access the php file by the NodeMCU. I'm currently getting this error: HTTP_UPDATE_FAILD Error (-103): Forbidden (403. It makes me think that I'm not using the right MAC address. When I flash the NodeMCU with the NodeMCU flasher I get 2 MAC address's, AP and STA.

When I use a script to get the MAC address I get a different MAC address. I've tried all 3 mac address's in my script and still get an error.

Here is my sketch. Edited for security..,:

Any help will be appreciated.
