Mass subscribe operation fails with http error
Hi,
We have a mailing list where the admin has configured a custom template: [list:user:action:invite] When inviting a user using Mass Subscribe, the operation fails with the error: HTTP Error 400: ('Connection aborted.', ConnectionResetError(104, 'Connection reset by peer'))
I have reviewed similar threads, including: https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/M...
I have updated the config in: /etc/mailman3/settings.py to contain: POSTORIUS_TEMPLATE_BASE_URL = 'https://mailinglists.ucl.ac.uk'
After adding that item, I've recreated the template and resubmitted the subscribe. But still get the same error.
What could I try next?

If you can access the database directly do
SELECT name, uri FROM template WHERE context = 'list-id';
where list-id is the mailing list's list-id, i.e. the list posting
address with the @ replaced by ..
Can you get the uri in a web browser or via, e.g., curl or wget?
