The host server cannot be contacted

[Helder Guzman]

Hi

 

I'm trying to add a citrix host (XenServer) to Citrix Studio, but I get the error The Host server cannot be contacted.

 

1. I'm able to ping the XenServer FDQN or IP from XenDesktop machine.

2. Web browser i can hit it.

3. FQDN is added to DNS Server

 

What am i doing wrong?

Did you try connecting via the IP address instead of the FQDN? Can you log onto the XS console via SSH?

[Helder Guzman]

I did used the IP Address. same error.

 

I was able to SSH to the XS.

From the CLI on the host, run the console manager (xsconsole) and check what networks it thinks is has. It may have dropped all but the primary management interface.

Other than the primary network interface, do you see any other networks listed under the "Network and Management Interface" menu?

thanks

 

I needed to add my the DNS server to the XenServer.

[Tobias Kreidl]

I was going to say there may be a name resolution issue. Are your VM networks all OK?

Several things here.

• XenServer 7.6 is long out of support so you need to upgrade to Citrix Hypervisor 8.2 LTSR.
• To use https to connect to the hypervisor from XenDesktop the certificate on the hypervisor must be trusted by the server running XenDesktop. Out of the box this will not be the case the certificates on the hypervisor are self signed. See https://support.citrix.com/article/ctx128656?_ga=2.159144442.1132053.1629821742-1118127804.1580377989 for instructions on how to update the certificate. Citrix Hypervisor 8.2 has improved support for installing externally trusted certificates, see https://docs.citrix.com/en-us/citrix-hypervisor/whats-new/whats-new-since-7-1.html#security-improvements
