Mark suggested earlier to change POSTORIUS_TEMPLATE_BASE_URL to "Set it to something like http(s)://server.domain". So I set the following in the settings_local.py file
POSTORIUS_TEMPLATE_BASE_URL = 'https://mailman3.emwd.com'
When I saw the SSL errors, I changed it to 'http://mailman3.emwd.com'. I now believe both settings were wrong.
This is what I have currently in settings_local.py:
POSTORIUS_TEMPLATE_BASE_URL = 'http://mailman-web:8000'
So this is correct? Yes?
I then restarted mailman-web:
/docker-mailman/docker-compose restart mailman-web
So the SSL error is now gone. I am back to the original error:
