Tor error "DNS resolving failed"

Question

Tor is last version. When paste any .onion address I see this:

ERROR: Not Found

While trying to retrieve the URL http://site.onion/ (normal onion address, that actually works fine):

DNS resolving failed

Your cache administrator is webmaster.

What to do? Help please. Thanks.

Answer 1

Onion services come and go quickly. It is no surprise that many of the ones that you might use are not functional. If you want to test your connection, a couple of ones that you can try are: facebook and the tor project.

Answer 2

This part of the error message:

Your cache administrator is webmaster.

Suggests that whatever you're pasting the onion address into is configured to use a caching proxy that does not understand onion addresses. You'll need to reconfigure your system to use a proxy that understands onion addresses, or to not use a proxy for connecting to onion addresses.
