Unable to create a user - "Connection Refused"?

[steveharman]

Apologies for spamming the issues page with this, I searched everywhere for a support forum without success (feel free to point out my obvious omission!)

• I've installed all officially listed dependencies
• I've followed three different installation guides (Digital Ocean, official, random user)
• I've tried two different freshly created Ubuntu installs (18, 16) and one on Debian (current)
• But I always arrive at the same blocker after issuing register_new_matrix_user -c /etc/matrix-synapse/homeserver.yaml https://localhost:8448 - after three different install guides on "different" OSes.

It feels more like a config issue than a code fault but I'm out of ideas and would really appreciate any assistance.

Thanks,

#synapse:matrix.org is usually a good first step for support questions.

In this case it seems like Synapse is either not running, or maybe isn't bound to that port (or isn't using TLS locally -- maybe you have TLS configured via the reverse proxy).

[dklimpel]

Either you have not a valid SSL certificate or your server is not listen with HTTPS at 8448.
One alternative, not very secure, is to use HTTP at 8008.

[clokep]

Also #3672 and the related bugs from that might be worth looking at.

[melroy89]

By default try 8008 (which can/should be used in combination with Nginx reverse proxy), so:

docker exec -it synapse register_new_matrix_user http://localhost:8008 -c /data/homeserver.yaml

Note: Where synapse is the name of your docker container.
