HTTPS pages not starting after Connection server Installlation

Hi All!

I've been administering a couple of Horizon installations in the last 2-3 years without any major problem, but now I have a really strange problem and I really don't know where to start.

Last week I installed a new instance of Horizon for a new customer. I started installing the Connection Server, release 7.7, on Windows server 2016.

After filling all questions during the installation, I rebooted the vm and at the restart the web console was not responding.

Actually the web server was working on http port, but obviously responding me with VMware logo and the message "Page not found, Try HTTPS" ( if it only worked….)

To clarify: I followed the standard installation, nothing different from "Next", "Next", and the info it needs. My user had administrator rights of the Windows server.

I noticed that in the folder C:\Program Data\VMware\VDM\dumps there were some dumps from Tomcat service. At every restart ot the Connection server service a dump appeared with the size of about half a GB. I tried to open those dumps with Visual Studio, but I didn't find any useful information.

I also looked at the logs in the log folder, but didn't find any evident error.

Since to me the problem looked like present with the HTTPS, I thought it was related to the default VMware, not trusted, SSL certificate. So I imported a public wildcard trusted certificate in the Computer Certificated in the Personal folder and gave it the friendly name "vdm", restarted the vm, but nothing changed. I actually made this procedure almost 10 times, I think I know how to do it.

All pages in HTTPS don't respond, at every restart tomcat creates a 500 MB log.

Did anyone had a problem so strange?

Any suggestion or help?

Thanks in advance for your time and support

Hi Giorgio,

Can you please check if the http and https port are been used by any other application.

You need to open command prompt and  run netstat -ano | find "443". This will list all the services used by port 443 with the PID like 1234 at right hand side.

Open the task manager and go to details tab and check for the application with the PID, which you got from netstat command.

Mostly i have seen IIS Service is the culprit, so check in services if World Wide Web Publishing Service is running. If yes than please disable the service and try to restart the Horizon View Services or take a simple reboot and check if that works.

Regards,

Rajesh

We have seen this issue due to TCP port 8005 conflict. If you have SCCM agent installed on the connection server(s), try removing them and restart the server.

if not, please attach the memory dumps of tomcat service for review.

Hi Kishoreg5674​,

thank you for the reply! I checked on the server and port 8005 is used by service "System", PID 4, so I think it's Windows.

I asked the customer if we can temporary disable SCCM.

Do you know the name of the service that needs to run on port 8005? So that I can search if this service can be reconfigured in order to change TCP port and let the customer use SCCM on the Horizon Connection Server

Thank you

Port 8005 is used by Microsoft Software Update Point client, which is a default port as per the below article

looking at the screenshot, i think this can be configured to use a different port. 

On HOrizon connection servers, TCP 8005 is the port on which the tomcat service waits for a shutdown command.
