fail when try to install connection server replica

[HussamRabaya]

Hi,

when i try to install replica , i recive this error however both servers the main and replica are new sever and join same domain with same domain account

any ideas why and how to solve it?

is there any relation with Secure ldap (ldap over SSL)???

when you started your installation, did you start the installation with elevated permissions?

[HussamRabaya]

yes the account is local admin in both server

and by the ways its 7.3.1

and i noticed the below error in the main connection server , im not sure if it related to this case

This is a Microsoft error, 

refer to the following technet article

Event ID 1220 — LDAP over SSL

[HussamRabaya]

that error related to port closed with AD

the strange thing the replica setup start successfully , and when it reach 100% it stop then revert back

connect to horizon/admin  you can see the replica server there but its saying the service is not working

just to add answer to anyone have the same issue

we have found that connection to AD is closed especially that we have found in firewall random ports are being used same as DFS ports

open these ports solve the issue
