Stopped at the door
Sorted by symptom, because when something is broken you know what you can see and not what is causing it.
The two checks that split almost everything
Before reading any specific page, these two take about thirty seconds together and they separate most of the categories below.
- Build a new circuit, then try a different door. If one address fails and another works, the problem is that address rather than your setup or the platform.
- Open any unrelated onion service. If that also fails, it is the Tor network and nothing address specific will help. If it works, the problem is narrower.
Stopped at the door
The page hangs or times out and never renders.
The checking your browser screen never finishes.
Credentials you know are correct are being rejected.
Something about the interface feels off and you cannot say why.
You sent funds and the balance has not moved.
Something asked you for information that does not feel right.
One rule that applies to all six
Do not go looking for a new address while something is broken. Anything that surfaces during an outage was placed there for people in exactly your situation, and the timing is not a coincidence. Whatever is unreachable will come back, and waiting costs nothing except patience.
