Managed to find a way. Created a docker container with all the
necessary stuff to run gobby and then captured what was going through
docker0.
Before gobby is started, only MDNS packets are seen. When gobby starts,
I still see no error packets, which is consistent with the previous
indications that this is a problem with the certificates, thus something
within the TLS protocol between client and server.
In the wireshark log that follows, the IPs that begin with 172.17.x.x
are the docker container where gobby is run. The IPs that begin with
69.141.x.x are the outside interface of the FreedomBox, where the
infinoted server runs.
This being a completely new instance of gobby, as soon as it was set up
it tried to connect to the server I specified (my FreedomBox). Tt then
generated the same error message I've been seeing (certificate has
expired). See previous emails in this thread for details.
I'm still at a loss to figure out why gobby is now failing to even
start when it was working great a couple of weeks ago. What can I
do about the certificates? Is there anything specific that I can try
that might be helpful in isolating this problem?
The questions in the previous emails still seem relevant. There seems
to be no good reason why a jabber web address is embedded in packets
between the gobby client and server.
Thank you for reading this far. I'm sure this problem can be annoying.
Is there no one else that has experienced this? No one using gobby?
The wireshark log is below. Best seen in a wide window.
