Operation not supported on Socket error

[Randall]

I'm porting from 1.2.0 to 1.4.2. I'm using mqtt_simple as a baseline but I'm connected to Google Cloud. I successfully create a socket;

net_mqtt_sock_tls.mqtt_client_tls_connect: (0x20020c70): Created socket 1

but when I try to actually call connect using this socket, is says that the operation is not supported;

mqtt_connect failed: -95 Operation not supported on socket

I'm not sure what could cause this.  I can paste how i initialize my client and broker structures if that would help.  I'm hoping if I can understand the situtations that cause this error, I might be able to narrow it down myself.

Hi,

-95 is EOPNOTSUP, and typically indicates that you have written wrong certificates to the device.

What certificates have you written to the nRF9160 modem?

Best regards,

Didrik

Same as before.  The certificate to Google IoT.

As it turns out.  I had peer_verify set to 2.  Apparently Google IoT doesn't support it. So setting it to 0 solved the issue.

Thanks, you can close the ticket.
