Wifi Kit 32 - HttpClient (https) not working after soldering the header

I know my problem looks really crazy. I tested a HTTPClient sketch using HTTPS successfully.
After soldering the headers I repeated the test and it fails (Wifi connection disconnected during the GET call). Using HTTP the test succeeds.

Is it possible that soldering (probably my soldering iron was not grounded) causes such a specific problem ? Everything else seems to work.

I repeated the same procedure on a second Wifi Kit 32 device with the same result.

Do you have an idea what happened ?


maybe this link have some help to you.


The problem is solved :

I tested with a BME 280 sensor connected with a 15 cm long ribbon cable.
The long cable disturbs somehow the WiFi communication.
After changing the experimental setup to a more compact, soldered circuit board everything works fine.
