Tor Check false negative

    • Closed (moved) Issue created by Trac @tracbot

    I started Tor Browser 5.5.2 (based on Mozilla Firefox 38.6.1) and routinely checked if I am using Tor before visiting any webpage. The test failed with the message attached in the screenshot.

      This is a problem with check.tpo, not a proxy bypass.

      Thanks for reporting.

      Below is the output from recent exitlists for this node. Around 2016-03-08-20-04-01 its ExitAddress changes, which roughly corresponds with the time of the report here. It took some time but check eventually caught up. The exit scanner considers its results valid for up to 48hrs and doesn't always rescan at each consensus (notice the times the test was performed on the ExitAddress lines).

      There's a detailed answer on stackexchange about false negatives worth perusing http://tor.stackexchange.com/a/873
