I am currently using HBMonitor. I had that issue. I had to change the config file see below. What I had to add is in bold. The page doesn't display correctly with more than 4 Masters but the HBlink status screen below is all I am really looking at.
REPORT_NAME = 'TARMA' # Name of the monitored HBlink system
CONFIG_INC = True # Include HBlink stats
BRIDGES_INC = True # Include Bridge stats (confbrige.py)
DMRLINK_IP = '192.168.10.236' # HBlink's IP Address
DMRLINK_PORT = 4321 # HBlink's TCP reporting socket
HBLINK_IP = '192.168.10.236'
HBLINK_PORT = 4321
FREQUENCY = 1 # Frequency to push updates to web clients
WEB_SERVER_PORT = 8080 # Has to be above 1024 if you're not running as root
