HTTP Error 404 after enabling the HTTP connection

Anonymous — Mon, 08 Jan 2018 08:36:25 GMT

Hi,

I completed a qliksense server installation and able to access to qmc using HTTPS (https://localhost/qmc). After logon and applied the license, I navigated to CONFIGURE SYSTEM->Proxies->Central Node to turn on the Allow HTTP. I restarted all the QlikSense services and try to access using HTTP (http://localhost/qmc). The following error is displayed. Please advise how to fix the HTTP 404 error.

Hi Hee,

so is port 80 available for Qliksense to use OR is an other app / process using it? E>G. IIS?

Hi Andy,

I do not think there is any other app using port 80. Other than netstat command, is there any other command allows me to find out ? Please advise.

See below the output with the netstat command executed on the QlikSense server.

Hi Hee,

where are you actually access from? On the server itself OR remotely?

try (http://servername/qmc). instead.

Hi Andy,

The previous two output is from the access on the server itself.

Please find below the output done using (http://10.1.1.10/qmc)

1) From a notebook

2) On the server

You could download and use:

TCPView for Windows - Windows Sysinternals | Microsoft Docs‌

It will show if something else, e.g. IIS is using local port http

Give it a go

Hi Andy,

I cannot find any process using Local Port HTTP nor 80 except the System (See below - 1st two rows). Is there any other detail I need to look for ? Please advise.

Hi Hee,,

so if system is listening on it then it's been used!! You have SQl installed so maybe you have SSRS too!.

You should change the default http in the proxy to say 81, and try that, you need to specify the new port in the url too.

Hi Andy,

It is not advisible to remove the system from listening to port 80. Correct me if I am wrong.

Is it possible to have Qlik Sense to co-exist with system to listen to port 80 or is there any workaround besides changing the default proxy with port 80?

Hi Hee,

Go to QMC and changed http port to an available one like 81.

Proxies ‒ Qlik Sense

You can go to QMC over https url even you checked to "allow http" option.

Hi Kaan,

Thank you.

Allow HTTP was setup as per stated in my first submission. I am looking for a workaround without changing the default port 80. Do you have any workaround ?

Why not just try changing the port as a test? You can always change it back again!!

Actually there is no workaround for it. Multiple application on same port is not possible for TCP.

Why are you hesitating to change qlik sense port to 81? It is the only way if you deny to change the port options of the application that is currently running on port 80.

Hi Andy,

I did try to test by changing the QlikSense HTTP Port # and it works.

The TCPView is showing SYSTEM ONLY and there is no way to identify which application is using the port 80. It seems like there is no other workaround except changing the QlikSense HTTP port. Can you confirm?

Hi Hee,

changing the port is the CORRECT option. Glad it works for you!

best Regards
