problem whit plexify installation

Good evening, I have the following problem, a few months ago after buying the AppleTV I performed the procedure to use Plex Media Server with Plexify and the procedure is successful.
After a few months following a blackout the AppleTV would not connect to the server so I tried to redo the initial procedure but with negative results, when I try to install Plexify message appears even after you have deleted the wrong password and set a new password.Ho He tried over and over again but he failed, how do I fix?
thanks a lot

Plexify is dead. You should look for alternatives, such as OpenPlex https://forums.plex.tv/discussion/108332/openplex-osx-app#latest

I have many problems with OpenPlex

Can you elaborate?
