I did a wireshark capture for port 6523.  The first surprising
result is that nothing showed up in the filtered capture when I started
gobby, but all the hosts in the Document Browser panel already had the
small red "x" on the bottom right of the icons.  Why would gobby know
that something was wrong before sending anything on port 6523.  Does it
send other stuff on other ports that prompt the red "x"s? Might this be
filtered/stopped by the firewall?  If someone can tell me what filter I
need to create to capture only the packets to/from one application
(gobby) I might be able to see it. Otherwise the flood of packets is
such that it's like finding a needle in a haystack.

When I double-clicked on the address of my FreedomBox I got the expected
result: "The server certificate is not trusted.  The certificate has
expired"

The first part is expected, after all the FreedomBox certificate is
self-signed, but it shouldn't be fatal.  The second one is puzzling.

I also got a 28 packet exchange betweein gobby and the FreedomBox, which
is included it its totality below, but packets 14 and 15 are
interesting: Change Cipher Spec. 

Inside the "Transport Layer Security" is this:

TLSv1.3 Record Layer: Change Cipher
Spec Protocol: Change Cipher Spec
    Content Type: Change Cipher Spec (20)
        Version: TLS 1.2 (0x0303)
	    Length: 1
	        Change Cipher Spec Message

Might this be the cause of the problem?  Has the FreedomBox recently
stopped dealing with TLS 1.2?  Might there be some mismatch that is
reported as the certificate having expired?  There are no error packets.
The address beginning with 192.168 is that of the internal computer
where gobby is running, the one beginning with 69.141 is the outside
interface of the FreedomBox.  The application data is encrypted, so no
way to make sense of it.

It is also interesting that in the data of packet 4 there is a reference
to "xmlns=jabber client" and
"smlns:stream="http://etherx.jabber.org/streams" and "to=<my
domain>.freedombox.rocks"

This brings up 2 interesting questions: Why is communication between
my local gobby and the gobby server on the FreedomBox even attempting to
contact "etherx.jabber.org, or at the very least why is that web address
there? and is there some bug that is using certificates for both
ejabberd (which I have installed) and infinoted?  Disabling ejabberd has
no effect.

There is also a port 37794 in this log.  What is the purpose of it?
Might it be blocked by the firewall?

Here is the complete wireshark output:  It is best seen on a wide
window.
