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: Telegram login widget in an Angular iframe error - Stack Overflow
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?
