Hi: I’ve been running a Discourse for the last months with no problems. I had to reset the host and now I can not get discourse working again. /var/discourse# ./launcher rebuild app Ensuring launcher is up to date Fetching origin Launcher is up-to-date cat: 80:80: No such file or directory cat: 443:443: No such file or directory cd /pups && git pull && /pups/bin/pups --stdin /usr/bin/docker: invalid reference format: repository name must be lowercase.

Try with deleting the ' characters in hostname and developper emails 'XXXXXXXXXXXX'

But I need those lines to be there !

Read what I said. You have added a #.

[image] Remah: #expose:# - "80:80" # http - "443:443" # https Should be: expose: - "80:80" # http - "443:443" # https

I didn’t make it that easy because someone needs to think how could such errors occur if this is true? [image] Juan_Carlos_B: that file was not modified at all … it’s same as it was when things were working :frowning: I’ve checked line by line, no errors …

Can't get discourse working again

Why this commenting out the command?

#expose:#
  - "80:80"   # http
  - "443:443" # https

It explains the error output:

cat: 80:80: No such file or directory
cat: 443:443: No such file or directory
