same, if you fix this can u tell me how u did?

This comes up on every thread about once a week (mostly Mondays). HTB uses dynamic hashes and sometimes they dont work. The hashes should change after every reset and be different on different VPNs - this means that hashes should be used as soon as you get them and that sometimes the process which registers the new hash in the scoring server will break.

If it is a box that is being hit with resets, it becomes imperative that the hash is used immediately as a reset will render it invalid.

Your choices are really:

  • Wait a while, repwn the the box and get a working a hash.
  • Report it to HTB via a jira ticket and get them to fix the problem.

This isn’t something that can be fixed by the forum or by tips from other users.
