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?
