The question here is, how much time does VDSM need to allow jsonrpc to connect and request a ping and list of VMs?
It depends on recovery logic in vdsm and it can take quite some time.
Please share vdsm logs so I could take a look?

the most likely cause is the recovery still in progress, however I was expecting a different error, so worth looking at the logs.
Isn’t the most likely cause by far a simple startup delay? We do open the listener “soon” and responds with code 99, but it’s still not instant of course
Bests,
