Describe your issue
Hello community,
I have a problem with the Outline app. When I install it and then open the frontend of the Outline app, I get a “502 Bad Gateway” error. I started the app manually using “sudo yunohost service start outline” and then saw the login screen once. After filling it out, I get a 502 error again.
In the notes of the Outline app it says:
To start server
- sudo su
- cd /opt/yunohost/outline
- sudo -u outline env PATH=/opt/node_n/n/versions/node/14/bin:/opt/node_n/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin yarn db:migrate
- sudo -u outline env PATH=/opt/node_n/n/versions/node/14/bin:/opt/node_n/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin yarn start
The problem here, however, is that the /opt/yunohost directory does not exist for me. I cannot execute the following two commands either.
What could be the problem here?
Many thanks for your help and answers!
