When something worked before and no longer works anymore, an important aspect to troubleshoot is change.
What changed recently? Did you install something new? Did you apply updates? Did you change some settings? Are you connecting from a different place?
Reviewing the differences in context between when things worked and when things no longer work is key and can help you identify responsibility (i.e. the component responsible for the issue) very rapidly.
- Here’s an example of an issue where change is key:
- “My Nike shoes hurt my right foot. They were fine until I put them in the washing machine.”
