nrF52 to Exosite

I am trying to set up a nrF52 -> Rpi v3 -> Exosite through CoAp as in the nrF5 iot sdk. The nrF52 to rpi works as I am able to ping the nrF52 through its global link address and the second LED lights up. Has anyone recently tried doing this lately, it seems that the exosite portion of the nordic example is out of date. Below are the messages I get on the nrF52 repeated several times.

0> [APPL]: DNS query failed.

0> [APPL]: CoAP server IPv6 address not available, sending DNS query...

If anybody knows of a solution to this or another cloud interface that is feasible, I would be grateful.

Yes, this means you don't have IPv6 connection. There is a couple of solutions to make the devices connect to internet: Setup IPv6 tunnelling. This will allow two-way communication with the devices…

Sounds like setting up an IPv6 tunnel would be my only option considering that I am attempting to send the packets through the RPi to the exosite cloud server. So, I am assuming that when the nrf52 says "DNS Response for hostname: coap.exosite.com, with 0 IPv6 addresses and status 0x0000C440" it could mean that my network doesn't support IPv6 not that the exosite server I am trying to access is faulty.

Yes, the example will query the Google IPv6 DNS server for the IPv6 address of the hostname coap.exosite.com. If you do not have IPv6 connection, it will not reach the server, and you will not get the address. You can try pinging the coap server using an online IPv6 ping tool to check if it's up and running.

I used an IPv6 tool and it looks like coap.exosite.com is up and running. Looks like the problem was on my end after all, thanks for your help!
