UI not accessible

Hi,

I am having issue with website. That is, I have deployed a WAR on tomcat and the UI part(Website/ Web Portal) is not accessible. I reach the login page and then at the upper right corner I get the following message ‘Server connection lost, trying to reconnect…’

I have 2 servers (2 IP address).
Consider Server A and Server B

On Server B, I have 2 tomcat.
Each tomcat is of different version and have different port number.

And On Server A we have reverse proxy which redirects to the specific server.

When I enter the url, and hit it, then the login page loads, but I am not able to do anything on it.
For Eg: https://abc.com/xyz/mywar/#login

abc.com - domain name
xyz - reverse proxy name
mywar - name of the war

I tried using context-path in tomcat and as well as in application.properties in WAR configuration. Both did not work.

Thanks in advance.
