Unable to access an app through http header virtual proxy - Qlik Sense

Thu, 03 Nov 2016 11:31:50 GMT

Hi,

I am in the process of setting up Qlik sense server for conducting a performance benchmark. I have followed the instructions provided in the appendix:

Provided required user access rules under License and Tokens
Created virtual proxy with required http headers
Installed http header modification extension for firefox

I am able to access the hub successfully through virtual proxy, able to see "Everyone" stream and all apps published under this stream.

When I access a specific app, I am getting error "An Error occured" with no further information. Have attached the images for hub access page and app access page which throws an error.

It seems additional access is required to open an app but not sure how exactly to achieve this.

Would greatly appreciate any pointers to solve this issue and move ahead.

Thanks,

Hi,

I have been able to get past this error with login access tokens and able to access app through Firefox and with http headers.

But still facing app connectivity issue through Scalability tool. It is throwing error:

System.AggregateException: One or more errors occurred. ---> System.ComponentModel.WarningException: Failed to connect to app. Error::Failed to connect to application

How do I resolve this and move further? What am I doing wrong? Request inputs to move forward.

Thanks,

I see you have a yellow triangle on the certificate, i.e. it's not fully trusted, this is most likely what is making the tool unable to connect. To solve this you have two options, either one should be fine, depending if using http is ok for you scenario or not.

Export the certificate from the server to the load client making the load server trust the certificate. The documentation contains instructions how to do this. When this is done you should have a green lock symbol in firefox.
Use http instead of https during the test:
1. Go to proxy settings and enable "Allow HTTP" under ports
2. Make sure you firewall allows port 80 (or whichever port you choose for http).
3. Test the connection using http instead with firefox to make sure it works
4. Uncheck the SSL flag in the tool.

Thanks a ton - after importing certificate, "connect to app" works perfectly. I am also able to connect through http after modifying proxy settings.

My apologies, it was probably stupid of me asking this question without looking at the documentation. Thanks once again!.
