I am trying to acces to some server, to get json responses trough https.

I get the responses perfectly the 90% of the time... but sometimes it launch this:

Rebooting...




I dont know why the system reboots...

And sometimes if i let the system rebooting and trying again and again to acess that server through https it says this:




I (3570) wifi station: Start https_request example
I (3580) wifi station: https_request using crt bundle

Traceback (most recent call last):

File "queue.py", line 167, in get

During handling of the above exception, another exception occurred:

Could anyone help me please ((((



Thank you a lot in advance

Looks like the hostname couldn't be resolved, which sometimes happens. Your own code really doesn't like that and crashes around the line indicated in the backtrace. You should handle a network failure properly, e.g. by retrying.

Thanks a lot for your response.

I am using exatly the same coda as in the https request idf example... the rebooting is normal there ?

What hardware and power supply are you using? It could be a power issue, since the power consumption is somewhat spiky, particularly with TLS.
