https_client certificate issue on thingy91

[rupcar]

Hello,

I am using the https_client example for Thingy91. Everything was working fine until I tried to change the website to send https requests to (from example.com to google.com). Now, when I try again with example.com, it gives me an error on the certificate, even though I am using the same certificate as before and it was recognized as valid just yesterday. It returns "certificate mismatch" and "failed to delete existing certificate, err -1163019603" as well as "failed to provision certificate" with the same error number. I identified that the error is coming from modem_key_mgmt_cmp(). Inside this function, key_fetch() is returning the error from nrf_modem_at_cmd(). I don't manage to get the meaning of this error - do you have any clue on that ?

Thank you,

Carole

update: I've tried to use a new thingy, did the "getting started on Thingy91" procedure and then uploaded the code again and it worked. Though, when I do the same using that previous used thingy, it still does not work. I'm guessing it's more an hardware problem then - do you have any ideas ?
