Qlik Sense 3.1 server issues this message on login to hub: "An error occurred Connection to the Qlik Sense engine failed for unspecified reasons. Refresh your browser or contact your system administrator."
Any assistance or ideas would be appreciated. I'm relatively new to Qlik; this is the first time we've tried to install 3.1.
We could solve the problem when we redirect to the central node. On proxy node, IOS gives the websocket error and can't connect.
Qlik Sense is accessing fine on my few clients but for a specific client it is not working when I asked to switch it some another internet access it is working fine. So I am sure its something relate to security. My question is do Client who is outside of your network need to open these ports in his machine or network too to access Qlik Sense ?
Hi Rohitk, I have the same problem. Works fine for 40 clients but not for 4 of them outside office. Did you solved the problem?
So those 4 clients are out of your network. You need to confirm three things from your 4 clients network provider or IT person:
1. Engine and Proxy section ports must open at our and in bound at end users
you can use telnet to test ports
2. Websockets are accessible
3. if any proxy server is there ask them do above settings into it.
4. your QMC=virtusl proxy=> white host list has all necessary values, like host name, fully qualified host name, IP and DNS name.
Please let me know if you will face any issue after doing above steps
Thanks,
Rohit
It worked for me when I white listed (see previous posts) the fully qualified server name.
We had <qlik server> in the white list, along with all the IP addresses etc.
But I had to add <qlik server>.<domain>.com.
Applying this caused services to restart, booting off any working connections. But within seconds I was able to log in to the hub from my desktop.
Hi ,
Please give the proper host white listing in QMC>Virtual Proxy>Advanced>put ur computer name in the Host ID list.
After applying this, Is issue still remains then kindly check the Qlik patches are updated as per your version use.
