Qlikview Access point show Message: "No Server"

[fashid]

Hi Experts,

I am working on a multi node migration project for Qlikview 12.5 version from on prem environment to azure cloud envronemnt  and after completion of all the steps we are unable to see the apps in the access point.  I have already followed all the steps mentioned in this post https://community.qlik.com/t5/Official-Support-Articles/QlikView-Organized-way-to-troubleshoot-quot-...

but still the issue persists . 

We are using IIS for single sign on .

All the services are running in green .

Can fetch the user also in management console.

No errors in Qlikview logs . 

It would be great if anybody could help in this .

The error means that there is no valid communication between the web-server and the server-services because the web-server showed this message and you admit that all services are shown as successfully running within the qmc. I'm far away from being an expert to such admin-stuff but I think it's caused from any access-rights and/or authentication issue between your services respectively the nodes.

Causes for it may be missing/wrong settings within the config-files, mixing of http + https communication, blocked ports, not trusting domains and more similar stuff ...

Thank you Marcus. Its really great to see your response. I have few questions when you say settings within the config file . could you specify which config file should i be focussing on . Also could you say a bit more on mixing http and https . It would help in further troubleshooting . The desired ports are also open except for 4735 which i beleive is not required.

server node 1) running Qlikview server and directory services

server node 2) running Qlikview server and directory services

Server node 3) running qmc, distribution services and directory services

server node 4) running settings service,offlineservice with IIS 

server node 5)running settings service,offlineservice with IIS 

This is the current setup 

should port 4747 be enabled on all the servers or only on the servers running the Qlikview service.

There are a lot of config-files for each service which might note be properly configured. It depends a bit on how the origin installation were performed and documented and how now the cloud-migration was done - if a manual reviewing of all these files should be the first step within the trouble-shooting.

Personally I assume that rather the access/authentication stuff would  cause the issue and each small part within the network like load-balancers, proxies, ports, different domains, group policies and so on could have an impact.

It's surely not easy to check everything that it really worked like expected. I think I would start by those things which are different between the old and the new environment - means has something changed like now are more nodes involved or the services are other distributed or now the IIS is the web-server and before was it the qlik web-server or similar.
