I'm trying to setup non-exit Tor Relay on ubuntu Server 16.04.1,but I'm getting the following warning:

Mar 21 11:37:28.000 [warn] Received http status code 404 (Not found) from x.x.x.x while fetching tor/keys/fp/58......88C

1 Answer 1


It's trying to lookup a relay that seems to no longer exist, specifically whatever relay corresponds to the 58......88C fingerprint.

It's possible that it does still exist, it just wasn't found on the directory provided by x.x.x.x.

This error is just a warning, it's not a fatal error and Tor will continue to function normally if it's the only error you've received.

  • Thank you so much for this help.How can I check that ,there is some clients that are connected to my relay so that I can be sure that its working?Thank you so much. Mar 21, 2017 at 17:46
  • Tor will output a heartbeat to it's logs every few hours to report on statistics, otherwise you can also send it a SIGUSR1 signal (i.e. run pkill -SIGUSR1 tor) to cause it to log the statistics right away or else use a tool like arm to view the current status of the relay.
