Hi,
You've got:
KALTURA_VIRTUAL_HOST_PORT="443"
Which is wrong. 443 is the default port for HTTPs. Since you want HTTP and do not have an SSL cert and key, you need:
KALTURA_VIRTUAL_HOST_PORT="80"
# Also, DWH is Data WareHouse it's a DB and should be 3306, the default MySQL port
DWH_PASS="3306"
# and, while 80 as password can work, I'd choose a better passwd:
DWH_PASS="80"
