Hi all
We are trying to access a page from Gemalto ELS61 using integrated HTTP client. We've got the following error:
AT^SJMSEC?
^SJMSEC: 1,0,1,0

As you can see the certificate verification is disabled. Can anyone help to solve this?
Hello,
I checked this address. In 'Server Key Exchange' the server wants x25519 elliptic curve which is not supported by this firmware on the module and that is why the module disconnects and displays this message.
It is supported in the newer firmware version but you need to contact your local technical sales person with this.
Best regards,
Bartłomiej
