You will be pleased to know I had the exact same issue and have managed to figure it out
I turned the firewall off on the VDI machines and on the Delivery controller i could not reach port 80, and was scratching my head for ages
I added a firewall rule to allow port 80 and still the same issue
Here is the fix
Open Gpedit.msc on the local machine
Navigate to Windows Settings>Windows Defender and Firewall>Firewall
Inbound rules and add a rule to allow port 80 inbound
Perform a GPupdate and then check the registration, it will now work
So it seems that even turning a firewall off does not turn it off, I spent around 20h getting to the bottom of this issue and Citrix could not resolve it for me.
