"Please disable popup blocker" message is displayed while trying to launch Ambari (

New Contributor

I am trying to launch Ambari dashboard but I see a message to disable popup blocker(which is already done). And I am taken to a page where it says "Site can't be reached" I can however see the tutorial page loading beside.

I am on windows 10

VirtualBox : Version 5.2.4 r119785 (Qt5.6.2)

Are you using HDF/HDP sandbox?

Are you able to connect to the ambari server Host (IP) and Port using terminal? Please check the following command output from your local machine where you are trying to open the Browser

# nc  -v  8080
# telnet  8080


On the ambari server host please check:

1. If the port 8080 is actually opened?

# netstat -tnlpa | grep 8080

2. Please check the ambari-server.log for any error/strange behaviour. Please share if you notice any error.

# less /var/log/ambari-server/ambari-server.log

Another way to quickly isolate if there is any Browser issue (OR) Network Issue (OR) Port Reachability issue (OR) ambari server issue. Please try to make the following Ambari API call from the host where you are running the Browser to see if you are able to connect to ambari server and able to make API calls?

# curl -u admin:admin -i -H 'X-Requested-By: ambari' -X GET

If above call also fails to connect then it means either ambari server did not start properly (or) there is some Hostname/Port accessibility issue.
