I am transferring files over Tor and I am seeing the following message in my Tor log file. Can someone explain what it means?
[warn] Query '[scrubbed]' didn't have valid rend desc in cache. Failing.
rend desc refers to a rendezvous descriptor. This is a special node for hidden services. In your case this information is missing and so it fails.
If I understand it correctly you can wait a few minutes and retry your connection. There is a chance that you'll get a rendezvous descriptor this time..
