Help on SSH Error 502: Bad Gateway

I’m trying to install HACS. And following the simple instructions.
But I can’t get terminal to work.
I get to SSH & Web Terminal, and try to paste the install command.
The terminal show nothing. Blank box and nothing but this … 502: Bad Gateway

I’m thinking it’s not installed correctly even though it shows up.

Trying to paste this in the SSH terminal to install HACS, but can’t

wget -O - | bash -

SO again nothing show up in SSH terminal. 502: Bad Gateway and you can’t type or paste anything.

Same problem here until I found this post. You need to go into the configuration and set a password between single quotes.
