If the URL for template is wrong, or Postorius is down for whatever reason, the subscription will fail with the error that you saw before.
Explain URL for template. You mean "POSTORIUS_TEMPLATE_BASE_URL"? That is not wrong. I am confident of that. It is back to "http://mailman-web:8000". I can successfully ping mailman-web:8000 from bash.
I logged out of Postorious and subscribed using the subscribe form on the info page and the change to the welcome template showed up. So it looks like being logged in as admin while trying to subscribe someone was what was causing the problem. Is that a bug I discovered? I suspect stopping-restarting and re-creating the template (idk, if you really did that) might have something to do with it. I am not sure if this is a bug unless you can reliably reproduce this.
This error is absolutely reproducible. It even impacts other list admins who are trying to use a custom welcome message and subscribing a member while logged into Postorious. Everything else is working fine on this server and I followed your directions precisely when I set this server up. Please help.
Thanks, Brian
