Well, there's only three users in CUCM:
AXL
JTAPI
RMCM
Of those three, UCCX only ever needs to update the last two:
JTAPI
RMCM
The RMCM account would be shared between both UCCX nodes in an HA pair, which means the installation of the second node would not need to touch it.  That leaves:
JTAPI
Now, in HAoW, you need to manually configure the second node's Call Control Groups; however, in HAoL these ports might be created automatically for you. I'm not sure, as it's been a long time since I've deployed HAoL and the documentation I'm finding isn't spelling it out too clearly.
It could be, that when you deploy HAoL for the first time, the second node attempts to create redundant CTI Ports for the existing call control groups, and that this is failing for one or more reasons.
A couple of things to try/check:
Retype your JTAPI user's password on UCCX first, and then on CUCM (both _1 and _2 users).
Check that your CTI Port DN range has double the capacity.  This is a tricky one, but maybe an example will help:
Say you had 10 CTI Ports on the node 1.  You then install node 2.  If your first 10 ports were the phone numbers 100X, then you would also need to have 101X available for the second node.  I think technically, UCCX will skip numbers it finds in use, but I wouldn't plan a deployment like that.  Make sure they're vacant.
Perform a data resync in UCCX to have it recreate any CTI Ports or CTI Route Points it needs to.
