Hello everyone, 

I am attempting to install Dspace 8 on Ubuntu 24.04 which is behind a kemp 
load balancer. I am wondering if I need to have port 8983 open on the kemp 
in order for Solr to work properly. I have installed the backend on a local 
machine and can see Solr admin and the HAL browser without any issue but 
now I am trying to do the same on a server provisioned by IT. I see a 
number of error messages related to the connection being refused in the 
Tomcat logs and it is preventing the webapp from starting. This following 
is an excerpt from localhost.log:

I am not clear on everything that is happening here and I am hoping that 
someone can provide some guidance. Initially I thought it was my use of 
server.xml in /conf/Catalina/localhost so I tried the other method of 
copying /webapps/ with the same result so that got me thinking about my 
actual setup.

Thanks in advance,
Marcia Johnson
