Can't connect to the hub from browser

[linoyel]

Hi,

I'm trying to connect to qliksense from outside (from the browser) with external server address but it doesn't work - error message attached.

What is done already:

1. The external server address is added to the White Pages in QMC in Virtual Proxies

2. All server firewalls are down

3. All ports in the server are open

What else could it be? Something with proxies? Authentication?

Please help!

QS server is OK for a 100%.

Something is wrong with the server itself (not QS server, just server)

Which version of browser r u using.

Thanks

The problem is not in browser either.

I think there is something wrong from the System side.

AND I KNOW THAT BECAUSE IT USED TO WORK!

The thing is that we had one server and then we bought a new one.

I've made QS server installation on the new server and transferred there QS projects.

From the system side, they're saying that they REDIRECTED THE SAME EXTERNAL ADDRESS from the old server to the new server, so now it's supposed to point to a new server's internal address and not to the old one.

I guess something went wrong in this redirecting. I'm not a system person, but maybe someone here can give me an insight so I can suggest to the System here what to do or what to check.

OK, so as I thought, the problem was from System side.

They DID NOT open all relevant ports for Qliksense.

All these ports have to be opened in the server's firewall:

https://help.qlik.com/en-US/sense/1.0/Subsystems/Server_deployment_and_configuration/Content/Qlik%20...

The main QS ports are 443 and 4244 so first thing is to check they are opened in the firewall.

If they are opened and there is still no connection from the outside (from the browser), more ports have to be opened:

those two ports are used as long as you are using NTLM based Windows authentication. Depending on the usage of https or only http one of those ports needs to be open.

4244	Default Qlik Sense Proxy Service (QPS) authentication listen port. This port is used by the internal authentication module in the QPS when using NTLM in Microsoft Windows. This port uses HTTPS for communication.
4248	Optional Qlik Sense Proxy Service (QPS) authentication listen port. The port is used by the internal authentication module in the QPS when using NTLM in Microsoft Windows. This port uses HTTP for communication.

Thank you guys for your help!
