Hello,

At this point I am able to detect 4 nodes with an IPv6 command from my Raspberry Pi (I have IPv6 connection with them). Nevetheless when I request a GET command to my 4 nodes with the CoAPthon library, I get response from 3 nodes but when I request GET to the last node I receive this error and my python script gets stucked. What is the error that I receive? How can I solve it?

Are you using client or server? How did you start them? Can you ping the address of the last node?

I am using a CoAPthon python client to request GET to my nodes. My nodes have a CoAP server and client into them to receive the requests. I am able to ping all the address of my 4 nodes as you can see here.

These are the 4 nodes addresses:

And here I ping the 4 addresses:

Ok, solved. I realized I used a bad IPv6 when I made the requests. So I obtained Network is unreachable.
