QlikSense port issue

[Mia20191021]

after I installed the QlikSense May release, I cannot reach the QS hub/qmc any more and this error shows. I cannot reach the local host either from server, cannot see a webserver running on Port tcp_443 (https). I go to the folder C:\ProgramData\Qlik\Sense\Log\Proxy\Trace, and found in the log file there is an ERROR "When contacting https://localhost:4242/ No connection could be made because the target machine actively refused it [::1]:4242

anyone help here? what should I check next and how to fix this problem?

Hello @Mia20191021 

Please check if port is opened:

netstat -ano | findstr 443
netstat -ano TCP | find /i "listening"
netstat -ano TCP | find /i "listening" | find /i ":443"

If port is listening please follow below steps:

It appears that one of the Qlik Sense certificates got deleted. Please run the following command: 

"C:\Program Files\Qlik\Sense\Repository\Repository.exe" -bootstrap -iscentral

you should be able to refresh the Qlik Sense certificates. 

This should allow you to regain access to the QMC. 

Thanks,

Hi Priya,
Thanks, but seems 443 is not listening, I only have 4432 here, so what should I do next?

Have you checked that all the Qlik Sense services are running?

Hello @Mia20191021 

Please contact your IT and open the ports.

Check the logs of the Repository service. Port 4242 is of the repository service. I suspect that there's a problem with that service. The logs should give you more information.

We have the same issue. It's probably caused by the change of an IP address of the server. 
All services are running.

From C:\ProgramData\Qlik\Sense\Log\Proxy\Trace\C0700_System_Proxy.txt:

When contacting https://localhost:4242/ No connection could be made because the target machine actively refused it 127.0.0.1:4242↵↓Unable to connect to the remote server

We virtualised the server (it's a VM on Hyper-V now) and changed it's IP-address. Now I get the same error as listed above. Where to find the log of the repository service? Or is this a known issue?
