Site pairing is unsuccessful across the HCX Manager

Products

• VMware HCX

Issue/Introduction

• HCX site pairing fails with the error "Please check the Remote HCX URL you are trying to connect and try again"

• SSH to the HCX Manager as user admin and run the command curl -kv https://<Target-HCX-Manager-FQDN/IP>:443

Environment

HCX

Cause

This issue occurred due to TCP 443 port blocked between the HCX Managers.

 

Resolution

• Verify that TCP port 443 is open in both directions between HCX manager appliances.

Check firewalls, ACLs or any network security appliances in between.

• If HCX managers route through a proxy, ensure the proxy allows TCP port 443

curl -k -v https://<HCX-Target-FQDN/IP>:443  --proxy <proxy-fqdn/ip>:<proxy-port>

• Re-attempt the Site pairing once the required ports are open.
