Pointing the root to /usr/share/allmon3 is not the solution. The page goes to the domain root but immediately gives a “Severe” warning, the nodes are not visible, and nothing works. I have read something similar in my extensive research.
From what I understand, the problem lies in relocating the websocket. Giving up is not in my plans. Not being an expert on the subject, it may take me longer than someone with knowledge, but I will get there. Throughout my 70 years, 40 of which I have spent in IT, there have been very few times when I have given up.
