I have an issue with the HTTPS functions on the SIM7000G module, especially with the certificate validation.
These are my at commands:
When I do this without certificate validation eg AT+SHSSL=1,"" it will succeed.
I have checked the certificate chain with Certificate Checker - Verify and Decode Intermediate Certificates | KeyCDN Tools and the chain is valid.
It seems a lot of people have issues related to this, but I can’t find a good solution.
I am using the 1529B05SIM7000G firmware.
