As a general question that really depends on what “level” of user a document is targeting.
I think for this particular page and the example you have given the answer is “no” - users of this page are likely to be sufficiently competent to understand that if they can’t find a particular tool they need to search for possible reasons.
Also for this document, I would tend to add troubleshooting as a section if there are LOTs of things that could go wrong. For just one likely issue, I’d tend to add a note “in place”.
