New PR60-1 - can login to UI, won't respond to commands

As you see from previous posts, we have ProXR boards running well at a site with wifi. We read/control them successfully with commands like:
192.168.2.130/relayON?relay=1

Bought a PR60-1 and PR60-150 with wired Ethernet module for new site.
NCD5500 and NCD base find them. We configured fixed IP addresses, didn’t change anything else.
Can login to the UI at 192.168.2.150, enter password admin. We see all pages.

Problem:
We have checked documentation, seems like access should be like our previous ProXR boards, with URL control.
We have tried everything -

is the HTTP access now not available? Do we need to switch to sockets? Which we assume would be port 2101? Would be disappointing since we have a solid working driver for the existing site, thought we could configure and go…

Thanks, appreciate a quick reply (we put this off too long) - short is ok! Have a good weekend.

Don’t spend time on this one. We have it working with sockets.
Maybe just respond whether indeed the HTTP requests have been deprecated.

We have another post that’s more important now about 0-10v DAC . Please look at that one.

Thanks!
