Thanks Mark,

What are your Django settings for MAILMAN_REST_API_URL, MAILMAN_REST_API_USER and MAILMAN_REST_API_PASS and do these agree with the [webservice] settings for hostname, port, use_https, admin_user and admin_pass in mailman.cfg in core and is the port open to the outside on the core machine?
greyarea-post is the mailman-core and exim server.
greyarea-web1 is the postorius and hyperkitty server.
On greyarea-web1, in django-settings.py,
MAILMAN_REST_API_URL = '[1]http://greyarea-post:8870' MAILMAN_REST_API_USER = 'restadmin' MAILMAN_REST_API_PASS = XXXXand both the above-named hosts are also included in ALLOWED_HOSTS along with localhost.
On greyarea-post, in mailman.cfg:
[webservice] admin_pass: XXXXX admin_user: restadmin api_version: 3.1 hostname: 0.0.0.0 port: 8870 use_https: noThe password and username are as on web1.
That all looks good.
Do you see REST requests from the Postorius machine in core'smailman.log and access.log?
Yes, there are lots of requests of the form:
[07/Jun/2020:15:00:01 +0000] "GET /3.1/lists?count=10&page=1 HTTP/1.1" 200 470 "-" "GNU Mailman REST client v3.3.1"I made a new list using the core CLI, and as a result of navigating directly to the list archive page I get to see:
[06/Jun/2020:23:00:02 +0000] "GET /3.1/lists/chbcdaily@ch-bc.org.uk HTTP/1.1" 200 365 "-" "GNU Mailman REST client v3.3.1"... but in neither case do I get a complete screen on the browser or 'follow-up' requests.
I don't have a file access.log on the greyarea-post.
Yes, that's actually a gunicorn log so would only be on greyarea-web1, but the mailman.log tells us the requests are getting to the core REST API, so we don't need that info.
On the greyarea-web1 I have mailmansuite.log with the last few lines:
File "/opt/mailman3/lib/python3.6/site-packages/mailmanclient/restbase/ba se.py", line 74, in rest_data response, content = self._connection.call(self._url) File "/opt/mailman3/lib/python3.6/site-packages/mailmanclient/restbase/co nnection.py", line 124, in call 'Could not connect to Mailman API: ', repr(e)) mailmanclient.restbase.connection.MailmanConnectionError: ('Could not connect to Mailman API: ', 'ConnectionError(MaxRetryError("HTTPConnectionPool(host=\'0.0.0.0\', port=8870): Max retries exceeded with url: /3.1/domains/ch-bc.org.uk (Caused by NewConnectionError(\'<urllib3.connection.HTTPConnection object at 0x7f5416db8518>: Failed to establish a new connection: [Errno 111] Connection refused\',))",),)') ERROR 2020-06-03 01:02:06,115 29002 django.request Service Unavailable: /postorius/lists/
OK. This is telling us that mailmanclient (the REST API Python bindings that Postorius uses to access core) is having trouble establishing a connestion to the core REST server, but it clearly gets there some of the time based on the mailman.log entries.
the uwsgi-error_*.log contains many lines of the form:
api: url is [2]http://greyarea-post.cam.ivimey.org:8870/3.1/lists?count=10&page= 1 api: url is [3]http://greyarea-post.cam.ivimey.org:8870/3.1/lists?count=10&page= 1My reason for thinking, in my original post, that the wrong host address is being used is that the ConnectionError above contains 0.0.0.0 in its url for /3.1/domains/... but 0.0.0.0 is only present as the listen address on the core web service and does not appear in the config for postorius.
The ConnectionError above comes from requests.request (docs at <https://requests.readthedocs.io/en/master/>). Client only provides a URL in the call to request and the URL is the baseurl + the path and the baseurl is MAILMAN_REST_API_URL which you have as http://greyarea-post:8870. Entries above have http://greyarea-post.cam.ivimey.org:8870/. Is that the correct FQDN?
I suspect a DNS lookup issue. How does greyarea-web1 resolve greyarea-post? You could try a FQDN that greyarea-web1 can lookup in DNS rather than relying on /etc/resolv.conf and/or /etc/hosts.
