"Un-Matched incoming response message" for /obs and Exception for /.well-known/core

[expliotlabs]

Hi,

I have a very simple script to query californium.eclipse.org. Im querying two URIs

1. /obs - This gives the Un-Matched incoming message log and keeps on retrying
2. /.well-known/core - This throws an exception.

Is there anything Im doing wrong? I have tried with a different library (in ruby) and it works so it doesnt look like it is a server or connection issue.

Below are the details:

---

1. script:

---

#!/usr/bin/python3
from coapthon.client.helperclient import HelperClient

c = HelperClient(server=("californium.eclipse.org", 5683))
r = c.get("/.well-known/core") # The other query is for /obs
print("r class {}".format(r.class.name))
