Do other samples (that do DNS lookups work)?
If they do not, you could try to set the address of a DNS server. You can see how in this comment: https://devzone.nordicsemi.com/f/nordic-q-a/50029/nrf9160-modem-firmware-v1-0-0-setting-custom-dns-server/235419#235419

Hi,

We are now getting a response from the modem in the AT Client firmware after updating the modem to v1.2.0. However for both the nbiot and nbiot_legacy_pco firmwares we still get cloud connect failed: 22 error with looping reboot.

Any further information or updates would be welcome!

Kindest regards,

Arjun

Hi.

When did you send the %XEPCO command?

You should send it before the device connects to the network.

The easiest way to do it is to use the thingy91_nbiot_legacy_pco image that is in the "Precompiled application and modem firmware" folder: https://www.nordicsemi.com/Software-and-tools/Prototyping-platforms/Nordic-Thingy-91/Download#infotabs

That version sends the %XEPCO command automatically before it tries to attach to the network.

Best regards,

Didrik
