Thank you for providing such great tutorial and repo. I've adopted into my project. However, I'm running into two practical issues. 1. My file server/AWS S3 bucket would return a 403 response if the file doesn't exist. The (resp > 0) condition in your original code will take this warning page as a firmware and download it. I can easily modify that condition. 2. I'm trying to work out a way for the device to compare the version of the firmware so I won't end up an infinite loop of downloading/rebooting. I'll let you know if I found some way.

In reply to Pietro. Hi, I have exactly the same issue. I checked your Git where you say the problem was probably caused by pointing to your file on a http:// link instead of a https:// link. With me however that's not the case. Any other ideas?

In reply to Nikos Mtrs. Hi, I am using a hosted file server. It's paid so it doesn't take much effort to set up. Basically, it's an Apache server with CPanel. Check out those paid domain services with hosting.

Hello, nice and helpful tutorial. I was wondering what kind of web server do you use and how it can serve the .bin file and make it accessible to esp32 for the update?
Do you know any examples/ tutorials on how to set up a server like that?
I am quite new to the software world , so any help will be welcome.

Hello. Nice and helpful tutorial. I was wondering what kind of external web server you used and how I can serve the .bin file from the server and make it accessible over the internet to esp32?
Do you have any examples/tutorial on how to set that kind of server?
