Can't Access Hortonworks Ambari (port 8080) with unbuntu 22.04 and 24.04

[#1]

I have been using, on Amazon AWS, ubuntu 20.04 version with Hortonworks (Ambari (port 8080) and file system (port 4200). In ubuntu 20.04, in the Network settings, I created Security Groups to enable access to ports:
      22 (Type: ssh, Protocol: TCP, Source Type: AnyWhere)
     4200 (Type: Custom TCP, Protocol: TCP, Source Type: My IP)
     8080 (Type: Custom TCP, Protocol: TCP, Source Type: My IP)
then I installed Hortonworks, and from the browser I can access Ambari by going to http://<<IP address>:8080 ; or going to Hortonworks filesystem by going to http://<<IP address>:4200

But now with unbuntu 22.04 and 24.04, I do the same steps above, but when I go to the browser, I cannot access Ambari by going to http://<<IP address>:8080; and I cannot go to Hortonworks filesystem by going to http://<<IP address>:4200

I appreciate any insight and help.

Thank you for your follow up, I appreciate it .

I have been using AWS with ubuntu 20.04 to do the following:

I create an EC2 instance, and in the Network settings, I create Inbound security groups rules for 8080 (Ambari), 22 (SSH), 4200, 9995 (zeppelin), 2222 (Hortonworks file system)

From port 22, I install Hortonworks sandbox,  then I can access port 8080 (Ambari) with user maria_dev, and I can access as well the other ports 4200, 2222, and 9995.

BUT now AWS supports only  ubuntu 22.04 and 24.04; which do not work to access Hortonworks like Ambari. I go  through the same exact steps that I used with ubuntu 20.04. I can access port 22 (SSH) only so I can install Hortonworks sandbox successfully. But I can not access ports 8080 (Ambari), 4200, 9995; I get errors from the browser:    502 Bad Gateway -- nginx/1.15.0

If it helps, I can send the exact instructions on a pdf file.

Thank you again!
