Thank you for the response. I've made sure cookies are allowed on all PC's and browsers but continued to experience the issue described.
While investigating further, the situation has unfortunately changed for the worse. Now none of the PC's on the same local subnet as the server can access FOP2 Manager using http://myserveripaddress/fop2/admin/. Every PC and browser is now prompted to log in as reflected within the attached screen shot. I've attempted to log in using all possible user names and passwords and receive an "Invalid Credentials" message as shown in the second screen shot also attached.
Here's the general section from my current fop2.cfg file.

I read the following post and confirmed the group and owner of the /var/lib/php/session folder is asterisk asterisk. The current permissions on that folder is rwxrwx---.

I completely understand your point that FOP2 Manager is a PHP application and should simply work from any internal PC or browser. At one point it did but it no longer does.
I've been trying to figure out what would cause FOP2 Manager to prompt for credentials. Are there any logs I can view that might provide some insight?
Thanks again.
