Could not fetch notices - Network is unreachable

I thought it would fixed it, but i don’t know why I can’t create the first account after installing. After try, this message was sent to my inbox:

I don’t see how that’s related to this thread from 4 years ago so I will move it to a new thread, but your server seems to not have outgoing internet connectivity, so fetching system notices from our server fails. You can ignore that error, or fix the connection issues.

If a proxy is required, use the standard environment variables in the systemd units for celery and uwsgi:

The installation was interrupted because default postgresql encoding was sql_ascii but utf8 is required. I thought that deleting the database and recreating it would fix the issue. Apparently the process ended successfully, but it doesn’t work.

I’ll check environment variables for proxy, that was another issue that was resolved during the installation, or at least I thought so. Thanks.
