@Shyam Mishra kindly provide some more details about the issue. It would be great if you can probably attach the screenshot of error message.

Also, check running below command using root user and tell us what do you see:

ambari-server status

You will find the logs of ambari at this location: /var/log/ambari-server/

Kindly, attach them as well.

Thanks,

Did you check the GCP VPC traffic ports access rules? Is the traffic allowed to/from VPC?

@Shyam Mishra

1. Please check if the "iptables" is disabled on the ambari server host?

# service iptables stop

2. Check if the port 8080 is listening on ambari server host.

# netstat -tnlpa | grep 8080

3. Please check from your remote host (Where you are running the browser to access ambari UI) to see if that port and IP address / Hostname of ambari is accessible?

# nc -v $AMBARI_HOSTNAME 8080
# nc -v $AMBARI_IP_ADDRESS 8080
(OR)
# telnet $AMBARI_HOSTNAME 8080
# telnet $AMBARI_IP_ADDRESS 8080

>>> If above fails then you will need to see if there is any N/W issue which is causing your ambari server UI to be accessed from your machine.

>>> In many scenarios there is a proxy involved in the browser (Means Browsers Proxy setting can cause this issue). So please check if your browser has any Proxy settings?

@Shyam Mishra Thanks for the further details.

Can you please check if your web server is up and running in your GCP compute engine? By default, it doesn't come with installed packages, so you have to install it separately using yum in Red Hat/Centos flavours and apt-get in Debian flavors.

Steps are below for Centos/Redhat machines:

#To check the installed package
yum list installed httpd
#To install http web server
yum install httpd -y
#To start the service of httpd webserver
systemctl status httpd.service
#Another way to start httpd service
service start httpd

#Once service is up and running restart your ambari server
ambari-server restart
#Now check the service status
ambari-server status

Once these steps are executed you can check your Ambari portal link and let us know the status of the problem.

Please Note: You will not find IPtables services installed on your machine unless you have exclusively installed it on your GCP machine.

Regards,
