I am having a heck of a time adding my Qnap to HA like I have my Synology connected. It seems to me it should not be that difficult:
Host* (used verified IP Address)
Username: Used valid username
Password: Used confirmed Password.
I have tried using an SSL certificate or not as well as verify SSL certificate or not. The default I tried was with both off but I tried all 4 combinations.
The default port is tcp/8080 but I can https into it with its self-signed certificate on tcp/443. I have logged into both tcp/8080 and tcp/443 (https) with the username and password I used.
Regardless of what I try, I get the error message: Failed to connect (which is not good for troubleshooting).
