Hyper-v replication between sites

Given: 2 sites with different IP addressing within the same domain. Each site of 2 failover cluster (site1_cluster1, site1_cluster2 and site2_cluster1, site2_cluster2)

I want to configure replication between site1_cluster1 site2_cluster1 and does not work, an error:

Event ID: 29230Hyper-V can not connect to the specified Replica server 'site1_cluster1'. Error: The operation timed out (0x00002EE2). Verify that the specified server is enabled as a Replica server, allows inbound connection on port '80', and supports the same authentication scheme.
Event ID: 32000
Hyper-V failed to enable replication for virtual machine 'VM1': The operation timed out (0x00002EE2). (Virtual Machine ID 1208DF9C-767F-4688-9AA2-B231A52DE339)

But at the same time, within a single site, the replication is: site1_cluster1 andsite1_cluster2.

And between the sites - not. Trackbacks are approaches between sites. Replication between domain controllers in different sites of the same work. Firewalls are off on seh hosts in the cluster.

Replication tune without certificates (Use Kerberos HTTP)

What could be the problem? Can Replicate hyper-v does not work between the sites?
