Oi.
I need to bump this. I have the same problem on an ubuntu 16.04 hyper-v server. I had the problem before, too. I installed Ajenti 2 first - which worked except from telling me "not a superuser", found out I wanted Ajenti 1.x, unsuccessfully uninstalled Ajenti 2, then installed Ajenti 1.x, completely uninstalled everything and reinstalled Ajenti 1.x, which did not work (SSL_ERROR_RX_BLAH as above). Overinstalling Ajenti V did not change anything, so I un- and reinstalled everything several times but could not change anything.

For all the initial installs and for most reinstalls, I used the quick cmds from the documentation that is linked on the product pages of ajenti.org.

Feel free to request any problem related logs or information you need to solve my problem.
