Troubleshooting 'diaspora-web.service Active: failed' & 'certbot'

Hi, i’m new to diaspora.
I want to set up an pod.

the command line can’t handle :

request : ‘systemctl start’

  • error prompt : ‘debian systemd[1]: Failed to start Diaspora social
    network (sidekiq)’

request : ‘certbot build command’

Everthing worked fine till now.
The ‘howtoforge’ tutorial guided me.
Please help me to figure this out.
