Re: [tor-dev] [404] :-( Retrieving Hidden Service Public-Key ...

The request to the dirport definitely has to come via tor not via a simple request to the dirport over the net.

Have a look in the HiddenService class here for an example:

https://github.com/drgowen/tor-research-framework/blob/master/src/main/java/tor/HiddenService.java

Its fairly easy to use this function if you just want to fetch the descriptor for an arbitrary HS. Have a look at the repository hidden service example. You just need a valid TorSocket and then you can call HiddenService.fetchHSDescriptor () to get it as a string.

I'm not sure that looks like a v2-desc-id, run in debug mode to see.
Result may not come unless query dirport from inside over tor
instead of clearnet. There was some change to that years ago
I think. Check...
