I agree with this, we need a setting for which interface for Gunicorn to listen on, and what Mailman Core sends out in the self_link attribute when responding to REST requests.
Exactly! :-)
Except if there were a bind_host setting to specify the host to bind
the REST API to and you set that to 0.0.0.0 you would have exactly
what leads to the situation below, so we need to understand what's
happening there (although I think I do - see below).

I did try with the gunicorn patch Mark mentioned (host = "0.0.0.0") and changing the cfg file hostname back to the full name of the host, and that now works!! -- in that the problem I showed earlier is gone.
However I then get another issue. From the mailman.log file I now see in the last few lines. For clarity I've numbered them like this "{1}":
{1} [22/Jun/2020:00:58:24 +0000] "GET /3.1/domains HTTP/1.1" 200 320 "-" "GNU Mailman REST client v3.3.1" {2} [22/Jun/2020:00:58:24 +0000] "GET /3.1/domains/ch-bc.org.uk HTTP/1.1" 200 215 "-" "GNU Mailman REST client v3.3.1" {3} [22/Jun/2020:00:58:24 +0000] "GET /3.1/domains/greyarea-web1.cam.ivimey.org/lists?advertised=true&count=0&page=1 HTTP/1.1" 404 26 "-" "GNU Mailman REST client v3.3.1"
At this point the browser screen reports "Something went wrong" and the message "HTTP Error 404: {"title": "404 Not Found"}"
Tracebacks would really help. You should be able to find them in the log configured as LOGGING['handlers']['file']['filename'] in your Django settings.
Previously, the process stopped at line {1}. Now that and line {2} is executed (AFAIK) correctly, but then line {3} is isssued. I have no idea why something is looking for "domains/greyarea-web1":
- Only the "ch-bc.org.uk" domain is listed in the reply to line {1}, as expected;
Go to your Django admin web UI and look at your Django Mailman 3 Mail domains. This will be at a URL like https://greyarea-web1.cam.ivimey.org/admin/django_mailman3/maildomain/
Do you see this domain there? If so, delete it.
- "greyarea-web1" doesn't appear in any lists I can show with the "mailman" cli command (and I think I tried them all);
But that's looking at Mailman core which is not where Postorius is getting this list.
- "greyarea-web1" doesn't appear anywhere in the source or config other than as the name of the host its running on or as an ALLOWED_HOST;
- I tried using "curl -X DELETE" (from the api docs) to delete a domain called that and it says no such list exists.
Again, you're talking to core, not Django.
My only possible clue is that I think, at some point in the journey of configuring mailman, I might have created a list called that on the host. However since then I have wiped the install files and reinstalled. I cannot make sense of this being the answer given the checks just listed.
Did you wipe the database on greyarea-web1?
I went looking through the python source and can see that the get() function does indeed throw a 404 exception if the domain isn't found, but I cannot see which code is parsing the reply from the first line
So I have two questions:
- How can I fix this problem?
See above.
- why does getting an 404 reply here cause the postorius web page to produce a "something went wrong" /404 and nothing else, when it could have simply reported that something had gone wrong with one specific domain;
Because the code isn't robust enough :(
...
Ideally, and this is icing on the cake, a listen address specification should allow multiple IPs to be passed in, in which case the server listens on all of them. I expect the python libraries already support this.
We could implement a bind_address setting that would pass to gunicorns --bind parameter anything acceptable to gunicorn, although multiple values are tricky as they apparently require multiple -b/--bind options and a single -b/--bind doesn't support a list of values.
But, I'm not convinced that this is something anyone needs. I'm still waiting for a response to <https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/message/7X7ATJYPR7TEWF4WA4OX4C7TNCJ7XXYV/>.
