using AT command AT+S.HTTPGET with option TLS,
what does the answer "AT-S.Skip CA" mean?
AT-S.Http Server Status Code:200
AT-S.Skip CA is a diagnostic message (can be hidden by reducing the verbosity) and indicate that the Authority Key Identifier of the certificate being validated does not match the Subject Key Identifier of the Root CA Certificate stored in flash. The system will load the next certificate in the chain received by peer and perform the check again, until the AKI of the certificate matches the SKI of the stored Root CA.
And about other post with hard fault issue with certificate bundle x3? did you check and see what is the problem?
