What to do if you can't reach an onion site
If an onion site won't load, first double-check the 56-character address - even a single typo will prevent Tor Browser from connecting. Sometimes onion services go offline temporarily or permanently, so trying again later or testing another known onion site can help you determine if the problem is on your end.
If you cannot reach the onion service you desire, make sure that you have entered the 56-character onion address correctly; even a small mistake will stop Tor Browser from being able to reach the site. If the address you have is shorter than 56 characters, it belongs to the older v2 onion format, which is no longer supported by the Tor network and the site is effectively gone. If you are still unable to connect to the onion service, please try again later. There may be a temporary connection issue, or the site operators may have allowed it to go offline without warning.
You can also ensure that you're able to access other onion services by connecting to DuckDuckGo's onion service or Tor Project's onion service.
