ERR_CONNECTION_TIMED_OUT after plugin install + rebuild

Hi,

I just tried to install 2 plugins on my week-old Discourse site. I added the Git links to the app.yml file and did a rebuild. Now the browser can’t connect to Discourse. The only thing I can think that I did wrong was that there was a prompt to clearly disk space… I can’t remember the wording, but I did that :pensive:

I’ve tried a few rebuilds.
I’ve tried commenting out the plugins.
I’ve checked the below from Googling other answers - no luck.

app.yml

## this is the all-in-one, standalone Discourse Docker container template

## After making changes to this file, you MUST rebuild
## /var/discourse/launcher rebuild app
