Hello world !
I beg your pardon for my English…
I’ve been having a connection issue to the server thinger.io with all of my esp32’s (and esp8266’s) for several months.
The situation :
I am installing a system working on an esp32 in a public building (high school). I set up an access point plugged in the school network and it worked well with my computer - theoretically the ports 25200 and 25202 should be open. Nevertheless, my esp32’s cannot connect to the cloud server (no problem with username, device_ID, credential, SSID or password).
I tried with a simple sketch (ESP32.ino from examples of the thinger.io library) with and without TLS, but it did not work.
I tried to set up the access point at home and it worked well (without TLS), same thing with my router at home.
The first capture below shows the connection debugging message without TLS (#define _DISABLE_TLS_) :
and the second one with TLS :
If anyone has an idea of what’s going on please let me know
