Hi We're trying to use this WIFI Manager (https://github.com/tayfunulu/WiFiManager/blob/master/wifimgr.py) to connect an ESP 32 device to a local wifi .

The WIFI Manager basically identifies all SSID's in the local area, starts a web server on 192.168.4.1, displays the different networks and lets the user select the one they want to connect to. This process is done on mobile browsers (Android or IOS phones and any browser).

This works perfectly in Android but IOS returns an empty POST response body. I used IOS Charles and can see the Response body with the correct information but it does not make it back to the server.

Image shows Response Header

Image two shows response body

This is what server received in Andriod (data in bold at end of stream):

client connected from ('192.168.4.3', 47754) Request is: b'POST /configure HTTP/1.1\r\nHost: 192.168.4.1\r\nConnection: keep-alive\r\nContent-Length: 39\r\nCache-Control: max-age=0\r\nUpgrade-Insecure-Requests: 1\r\nOrigin: http://192.168.4.1\r\nContent-Type: application/x-www-form-urlencoded\r\nUser-Agent: Mozilla/5.0 (Linux; Android 7.0) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/83.0.4103.106 Mobile DuckDuckGo/5 Safari/537.36\r\nAccept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,/;q=0.8,application/signed-exchange;v=b3;q=0.9\r\nX-Requested-With: com.duckduckgo.mobile.android\r\nReferer: http://192.168.4.1/\r\nAccept-Encoding: gzip, deflate\r\nAccept-Language: en-US,en;q=0.9\r\n\r\nssid=mywifi&password=abcdef1234'

This is what the server received in IOS (no data at end of stream):

client connected from ('192.168.4.2', 64482) Request is: b'POST /configure HTTP/1.1\r\nHost: 192.168.4.1\r\nOrigin: http://192.168.4.1\r\nContent-Type: application/x-www-form-urlencoded\r\nAccept-Encoding: gzip, deflate\r\nConnection: keep-alive\r\nUpgrade-Insecure-Requests: 1\r\nAccept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8\r\nUser-Agent: Mozilla/5.0 (iPhone; CPU iPhone OS 13_5_1 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Mobile/15E148 DuckDuckGo/7\r\nReferer: http://192.168.4.1/\r\nContent-Length: 39\r\nAccept-Language: en-us\r\n\r\n'

I realize the Charles response header and data are different then the IOS paragraph above but it is the same result. I've made tried Safari, Chrome and FF on iphone all with same results. I've made sure that privacy setting are set to allow third party data but maybe there is another spot I missed. Provided the Form action code below (def handle_root(client) which puts up the screen to display all the local wifi networks and below that the web server start (Def start (port=80)).

Thanks, Jim
