Mailman folk --

I've recently completed a complete install of the mailman3 suite on a Debian VM in Google Cloud (GCP). I used the excellent directions given here: https://wiki.list.org/DOC/Howto_Install_Mailman3_On_Debian10

Most things appear to work. Postorius is working, and I can create accounts, email lists, etc.

I have two problems. One is with getting list mail out of GCP. I am working on that. The issue I don't know how to address is a problem with hyperkitty. Nothing is being archived. When I send an email through my test list, this message shows up in the mailman log:

Jan 04 11:57:26 2022 (806) Exception in "hyperkitty" archiver

Traceback (most recent call last):

File "/opt/mailman/mm/venv/lib/python3.7/site-packages/urllib3/connection.py", line 175, in _new_conn

(self._dns_host, self.port), self.timeout, **extra_kw

File "/opt/mailman/mm/venv/lib/python3.7/site-packages/urllib3/util/connection.py", line 73, in create_connection

for res in socket.getaddrinfo(host, port, family, socket.SOCK_STREAM):

for res in _socket.getaddrinfo(host, port, family, type, proto, flags):

socket.gaierror: [Errno -2] Name or service not known

This triggers a bunch more tracebacks.

Then I get this:

Jan 04 11:57:27 2022 (797) Connection to HyperKitty failed: HTTPSConnectionPool(host='www.XXXXX.dev <http://www.xxxxx.dev/>', port=443): Max retries exceeded with url: /archives/api/mailman/archive (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f2114e14e10>: Failed to establish a new connection: [Errno -2] Name or service not known'))

I think this second error is just mailman3 reporting that it had trouble with hyperkitty because of the first error.

How can I get more information about what connection is being attempted when this failure occurs?

Thanks!
