How can I check log errors for discourse?
http://[your_domain]/logs - assuming Discourse is installed. If not, you’ll need to be more specific.
It is not installed I followed digital ocean instructions and have problems, I get Unable to connect.
Where it is on the server?
Which DO instructions did you follow? They have multiple Discourse instructions, and not all are correct/up-to-date.
I found it
cd /var/discourse ./launcher logs app
it showed error with letsencrypt email,
sudo nano containers/app.yml
i forgot to remove # in front
Just a heads up, this is the first line of that article:
Warning: This article is out of date and no longer works. Please read the updated Discourse article instead.
Please make sure to read instructions carefully to avoid broken installs.
