Can't get discourse working again

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.

“run” and “bootstrap” commands do the same :frowning:

You can examine the output of this script with 
LESS=-Ri less /tmp/discourse-debug.txt

BUT FIRST, make sure that you know the first three commands below!!!

Commands to know when viewing the file with the above command (called 'less'): 
q              -- quit
/error<ENTER>  -- search for the word 'error'
n              -- search for the next occurrence
g              -- go to the beginning of the file
f              -- go forward a page
b              -- go back a page
G              -- go to the end of the file

Make sure the settings highlighted by Doctor are correctly filled and not empty.

For example: DISCOURSE_HOSTNAME: mydomain.com (note separator should be : not =)

You can check the syntax with an online YML validator: http://www.yamllint.com/

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 …

Here you have:

## Any custom commands to run after building
run:
  - exec: echo "Beginning of custom commands"
  ## If you want to set the 'From' email address for your first registration, uncomment and change:
  ## After getting the first signup email, re-comment the line. It only needs to run once.
  #- exec: rails r "SiteSetting.notification_email='info@unconfigured.discourse.org'"
  - exec: echo "End of custom commands"

Try with deleting the ' characters in hostname and developper emails

'XXXXXXXXXXXX'

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

But I need those lines to be there !

Read what I said. You have added a #.

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?
