"Failed listening on port 6379 (TCP)" stops installation

Hi! Thank you, and this did help very much. However, I am also encountering this problem: when running ./discourse-setup the site returns this:


I do have the A address properly setup in my DNS records. Ports 443 and 80 are not in use and available when I run the setup command.

When running curl https://mywebsite.app-
curl: (7) Failed to connect to mywebsite.app port 443 after 33 ms: Couldn’t connect to server

After killing what was using port 443 (it was being used during setup), and running curl again, it returned the same thing (the only difference being the times- 33ms → 2ms before outputting)

Raw log - abc - Pastebin.com

(I’m not sure if it’s supposed to output Discourse installed or something along those lines, however it does not do that)
