Problem Description

After loading BasicOTA from examples the esp8266 port appears in ports and I can ping the device at its IP address. However when I try uploading the same file over wifi I just get the message
19:21:29 [ERROR]: No response from device
When I enable OTA debugging and use Putty to monitor debug, the debug shows that the Wemos is seeing the update request but I cannot see why the other errors occur

Just allow Pyhon.exe to use network in Firewall Settings

Can You please check if there is "hole" in the firewall? IMHO this kind of errors is because of Windows firewall block.

Doesn't the ping working and the putty debug response mean it's not a
firewall issue? Or am I wrong?

Ping is ICMP protocol (nothing to do with OTA), and Putty is just TCP client. Can You please try OTA with disabled firewall?

I edited the following table which originally showed Firewall On for PPPoE (all others were off). Still get exactly the same response when I try wifi update. I tried another Wemos and same result.
I think you must be right about it being related to router setting as the problem only occurred when my broadband company installed a new router. Is there another setting which might be relevant?

@samlewis02 Did you remove power from the ESP after flashing the OTA-sketch? You have to remove power, then reapply it before OTA starts to work -- it's because something gets stuck in the hardware whenever you flash a sketch via serial and resetting the hardware fixes it.

I think the table in last email might have been messed up. I will try again.

Can You please check AP Isolation mode on Your AP (https://www.techwalla.com/articles/what-is-ap-isolation) ?

Pablo2048 on 11 May 2018

Not a core issue, closing.

Doing a OTA update will open a port on your computer. Then it sends a request to the esp8266 to download the image from your computer and flash it. That you are able to ping the esp8266 is not enough. The esp8266 also needs to be able to reach your computer on the temporary opened port to download the image. Probably you have a firewall that prevents the esp8266 from doing that download. Disable your firewall (and maybe antivirus) and try again.

A common problem is the selected network profile when joining the network on a Windows PC, i.e. as "private" or "public" as different firewall settings are applied. If connected as "public", the firewall is (typically) configured more restrictive and may not allow the ESP8266 OTA to connect back to the PC. This is also true for different Wifi networks, e.g. 2.4GHz and 5GHz.

In my case it was my antivirus software, Eset Internet Security that blocked the traffic of python.exe and ESP8266. After turning that blocking off upload works like a charm.
