1.) Is your WoW updated to the latest version? It's clearly stating you aren't but figured I'd still ask.
Use this feature in the battle.net app to check.
2.) Did you manually download honorbuddy or use the auto update feature? Sometimes auto updating has caused issues like this for me in the past. I always recommend doing a clean install (uninstalling your old honorbuddy and reinstalling) after every update, simply backup your settings/routines/bots folder by copying them somewhere else before hand and throw them into the new installation folder.
Mine works now what i did was i went into my control panel and i uninstalled honorbuddy then went back to the "buddy downloads" and downloaded it again and now it works
