ESP8266 Community Forum

Hello folks,

The sample ESP-HTTPD mostly works for me but there are some corner cases that don't and I was wondering how folks out there dealt with this.

• In the browser, if I typed in some HTTP address, the index page would show up most of the time but occasionally, I would receive an ERR_CONNECTION_RESET. And if I waited a while, the browser would refresh the esp8266.nonet page and then I would see them cats again. Has anyone fixed this intermittent problem?
• However, if I typed in some HTTPS address, there would be no redirect to esp8266.nonet. Is there a fix for this as well?

I'm probably going to keep investigating but if anyone has any ideas, I'm all ears!

Regarding the first problem, here's what I see with wireshark:

• Phone sends GET request
• ESP8266 responds with a 302 to esp8266.nonet
• Some SYN/ACKs between phone and ESP8266
• RST sent from ESP8266 to phone
• And the above two steps repeat itself a few times

Any ideas why the ESP8266 is sending a RST?

I can acknowledge this issue: I've seen it myself but have been too busy to spend any quality time trying to figure out what causes it. Just for my info: are you using the nonos or the FreeRTOS version?

I think you are stuck with this behaviour. Browsers do not redirect https addresses which I expect is a security issue so that you you can not be redirected from my.bank to scammer.bank.
