Good day! Recently, I updated ManageEngine ServiceDesk from 9300 to the latest version 10016. It began to slow down a bit. I found out with the help of the developer’s tools, that in the browser it was trying to access port 8081 on https 443, what kind of port it is, can it be turned off. If I redirect it to 443 on my proxy, will this break some functionality?

The second question, I remember earlier, was a certain guide, according to recommendations for setting parameters for java, but it touched version 9300. Are there any new recommendations for version ManageEngine ServiceDesk 10000 and higher? Thanks in advance for your reply.
