what version of vSphere Replication and what version of vSphere are you using?
Please read the documentation for the respective vSphere Repliaction version, for 6.5 e.g. here: Register the vSphere Replication Appliance with vCenter Single Sign-On
There you can read that you need to enter just the IP address or FQDN of the server that runs the lookupservice. That is the PSC (if you use an external PSC) or the vCenter server (if you have installed it with an embedded PSC).
vSphere ESXi 6.0 U3
vCenter 6.0 U3
vSphere Replication Appliance 6.1.2
I´ve tried to register with the IP and also with the FQDN ans it´s impossible.
Everytime appears the message: "Unable to obtain SSL certificate: Bad server response; is a LookupService listening on the given address?"
I think port 7444 is only used by vCenter 5.5, and starting with 6.0 it is on the standard https port 443.
... and are you sure that you are not using an external PSC?
No... I´m not sure. That´s why I want to know the url of the lookup service.
I´m not the administrator of this platform. I´m only installing and configuring th VRM
How can I know this address???
The below step needs to be executed on the relevant PSC machine :
Windows based PSC:
"C:\Program Files\VMware\vCenter Server\vmafdd\vmafd-cli.exe" get-ls-location --server-name localhost
Appliance based PSC:
/usr/lib/vmware-vmafd/bin/vmafd-cli get-ls-location --server-name localhost

To find out PSC system from your VC : https://www.virtuallyghetto.com/2015/04/vcenter-server-6-0-tidbits-part-3-finding-all-deployed-platform-services-control…
Finally I noticed that the PSC was in another machine.
Thanks to all for your help.
