Some onionsites are returning 0xF2 errorcode but their servers are online. Is the middle node blocking Tor's description request? Details: 0xF2 — Introduction failed, which means that the descriptor was found but the service is no longer connected to the introduction point. It is likely that the service has changed its descriptor or that it is not running. PoC: foreach lists in OnionServerLists.txt: do code := query OnionURL if code ne 200 log fi endfor One of those URL: http://zkyo47fhjhfstn3a2bnaj3ir5rcv7f6vo3cuktpjpiw2mxfjqakqipyd.onion/ Try to open above example URL on Tor Browser 10 per 2 hours.
