For some reason the espota.py script doesn't work from my computer anymore. I haven't used in a while so I don't know what exactly I changed but this is the debug output I get when running espota.py from the console with -d argument:

Code: Select allPS C:\Users\username> python.exe C:\Users\username\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\2.3.0/tools/espot

On my laptop however that I rarely use for coding it works just fine. On both machines I am using Python 3.5.2 (python.exe --version). I also tried reinstalling the esp8266 inside the Arduino IDE. The problem shouldn't be related to my network or the ESP8266 I am using because it works on one of two machines, so it must be a problem with my computer somehow.

Does anybody know how I can fix this?

Thanks for reading!

- Mon Sep 05, 2016 10:50 am #54537 Yes, I forgot to post the output I get on the ESP8266 Serial console:

Code: Select all[OTA] Start

[OTA] Progress: 0%
[OTA] Error[2]: Connect Failed

[OTA] Error[4]: End Failed


So IP address must be fine. I tried disabling the firewall completely which didn't help either.

Edit: Nevermind, I forgot to click "OK" after disabling the firewall. It blocked python.exe on public networks, which apparently my home network gets identified as...

Thanks for the suggestion!
