[Koha] IP Address Changed

[Jack Morash]

We are experiencing an "Error:IP Address Changed. Please login again." 
issue on our system. Does anyone have a solution for this issue?  We have heard there is a patch but we are unable to find it.

We are running:
Koha 3.16.04 but was having same issue on 3.12

Server is an Amazon EC2, t2.micro, instance (Xeon processor w/ 1 gig memory) and an RDS instance running MYsql 5.5

OS is Debian flavored Linux.

Thanks in advance for your assistance.
Jack
