Jo ! Can you check out my result, please. I got task failed, but all worked fine I was able to get response from each servers verified connectivity from loadbalancer to each httpd service.
I can repeat this exercise if you wish but I am pretty sure smth is wrong with verification. Additionally my lab broke and I had to restart exercise maybe this caused an issue.
Sorry to hear that. We will check and get back to you.
Hi @andrzej, you were right. There was an issue with the validation. We have fixed that now. Your task has been marked successful. Thank you for your patience.
@mmumshad : I also received below output
Task Status - Failed
php-fpm service is not running on App Server 1 php-fpm service is not running on App Server 2 php-fpm service is not running on App Server 3 website is not setup correctly as its not working on LBR URL
Although i could get output below when checked using Host1 option
PHP Test Welcome to xFusionCorp Industries !'; ?>
Could you pls look into it
Hi, guys!
Please help with this challenge
Day by day traffic is increasing on one of the websites managed by the Nautilus production support team. Therefore, the team has observed a degradation in website performance. Following discussions about this issue, the team has decided to deploy this application on a high availability stack i.e on Nautilus infra in Stratos DC. They started the migration last month and it is almost done, as only the LBR server configuration is pending. Configure LBR server as per the information given below:
a. Install nginx on LBR (load balancer) server.
b. Configure load-balancing with the an http context making use of all App Servers.
c. Also make sure Apache service is up and running on all app servers.
d. Once done, you can access the website using StaticApp button on the top bar.

but with curl I get ERROR that port 80 refused
curl: (7) Failed to connect to 172.16.238.10 port 80: Connection refused
You are missing the ports. What port is the apache service listening on for each app server?
pls, help me with the same task - level 4 linux - Install and Configure Nginx as an LBR.
i think i have done it right, i do see the âwelcome to xfusion corp industriesâ
here is some screenshots:
on all 3 app servers, in httpd.conf
and on stlb load balancer:
whatâs wrong?
This looks like a validation error, but the app works with the expected response (Welcome to XFusionCorp Industries!)
I even tried with just the app server names (without FQDN) and also by their IPâs, all got validation checks failed.

I tried your configuration (just the proxy part) in the main nginx configuration and it worked. Note in the main nginx configuration there is a listener on the ipv6 port as well which you donât have.
Ok, I have added the lipv6 listener too .
upstream myapp1 {
server stapp01:6300;
server stapp02:6300;
server stapp03:6300;
}server {
listen 80;
listen [::]:80;
location / {
proxy_pass http://myapp1;
}
}
The validation still fails @al1
Where are these changes being made?
inside /etc/nginx/conf.d/lbr.conf
That will be conflicting with the configuration in /etc/nginx/nginx.conf
Yeah, it worked for me now, after making the changes directly inside nginx.conf file itself.
But when I did the change inside conf.d/lbr.conf, I made sure I commented out the same settings in the nginx.conf file and on top of it, we get the desired result expected, when we click on the App button on top right side.
But no issues, validation is now successful, thanks @al1 for your insights.
You do not change the configuration at all on the app servers. All configuration is done on the load balancer server Re read this thread, you will see you are missing the ports that the application servers are running on. They are not running on port 80.
yes! thxn, its done now!
