Hi,
Glad I could help.
This is a forum so not really bug tracking so you cannot close the thread. I think the conversation is automatically closed when the discussion reaches a certain age - 6 months????
It's not a bug so no to raising a Tracker issue. If you can find a good place to add this information in the documentation, you can edit the page and add it in. Maybe you want to add it here - https://docs.moodle.org/38/en/Configuration_file#Setting_.24CFG-.3Ewwwroot_correctly
Cheers
