timeout for request
Hello! Began to use your library, and noticed that sometimes openweather site doesn't answer on the request. In that case Arduino hangs for 60 secs:
Requesting weather information from OpenWeather...
The connection to server is secure (https). Certificate not checked.
Connection failed.
Duration of OW request:60098
(If I try just to disable internet access for the MCU - it hangs only for 18 secs).
A quick look into the OpenWeather.cpp file shows only few 5 seс timeouts for "Sending GET request to " and 5 seс timeouts for "Client timeout during JSON parse".
Tell me pls, what the timeout should I decrease to not wait for 60 secs? Is it possible to do the appropriate configuration setting?
Thank you for the library !)
There are 5s and 8s timeouts but none for 60s. The delay may be in the board package WiFi functions. Which processor are you using.
I suspect you will need to add debug messages to the library code to see which WiFi library call is the culprit.
Thank you for your answer!
Turned "#define SHOW_HEADER" on. But today openweather site answers well:

So I ask you to wait untill errors appear )
Hello Bodmer! Here it is!:
22:10:42.385 -> Requesting weather information from OpenWeather...
22:10:42.385 ->
22:10:42.385 -> The connection to server is secure (https). Certificate not checked.
22:11:42.652 -> Connection failed.
22:11:42.652 -> _Duration of OW request:60271 / sec:60. City name length:0 - it's my code's answer_

22:11:42.652 -> _No answer from OW server! Exit! - it's my code's answer_
Ping.averageTime to 8.8.8.8 =82.21 ms, so internet connection is normal.
What should I to do more?
It looks like the delay is in the board package code, wiating for a connection that does not happen.
Unfortuantely there is nothing the library can do unless a way is found to shorten that timeout.
It looks like the timeout can be set for a connect now. It did not used to work but this issue seems to be fixed now.
Try changing this line to: if (!client.connect(host, port, 20000))
The timeout should then be 20s.
Hello Bodmer!
I'm very sorry, but in the end I didn’t fight the delays, but rewrote my sketch with ESP RTOS Tasks. So delays are don't matter for me; and ticket can be closed.
Thank you very much and for your help and for your great work!
