Hello, I've seen some similar problems, but have not yet found anything that would work for me.
I just installed Mailman3-full from debian stable repository (Mailman 3.2.1 to be precise). Mailman itself is working, also are all mailing lists imported from Mailman 2.1. But I just can not get the web interface of Postorius to work. I did manage to get it running through apache2 after I figured out what I had to remove from the old site config and replace it with the stuff in the automatically created config. Upon loading the site, I was able to log in and verify the mail address, but it kept showing that it wasn't able to connect to the REST API.
I double and triple checked, that mailman-web.py and mailman-hyperkitty.cfg contain the same API key (api_key in hyperkitty and SECRET_KEY and MAILMAN_ARCHIVER_KEY in mailman web), but that didn't help. I also saw a recommendation, that it can cause problems, when the API key uses symbols like / so I switched it to _ in all three places, but that didn't help. The configuration for mailman, mailman-web and hyperkitty all are set to using https, switching them to http doesn't solve any of the problems. Meanwhile, the site only shows "Internal Server Error" even though I did not change anything. But probably not that relevant while it can't be used either way. What I can provide on logs:

So everything seems to be starting smoothly.
