How can I run a phoenix app on port 80 in dev mode on my local machine?
I need to get a telegram login widget working and unfortunately it only works if I run on port 80 – see this discussion to understand why: https://stackoverflow.com/a/58016947/1701170
In any case, I’m trying to get my app to run locally on port 80, which I have done by adjusting the port to 80 in my config/dev.exs file. But I’m getting an error relating to Postgres:
[error] Postgrex.Protocol (#PID<0.570.0>) failed to connect: ** (DBConnection.ConnectionError) tcp connect (localhost:5432): non-existing domain - :nxdomain
Does anyone have any idea what is going on here?

Ok, so I got past the Postgres problem. It turns out that when I edited my /etc/hosts file I removed this line;
127.0.0.1 localhost
Once I put that line back in and then restarted my MacBook I was successfully able to run mix ecto.reset and the Postgres connection stopped giving me problems.
The next issue was making sure I used sudo to start my dev server:
sudo mix phx.server
