EBS 12.1.3
11g
OL6
Hi ALL,
We have EBS 12.1.3 installed on remote datacenter or in Oracle Cloud.
We been using this for almost a year now.
But lately we encountered issues. Our forms get easily killed or disconnected with error below, when we connect from our office.

But if I connect from my home internet (isp) my form is not being killed or disconnected fast.

And if I have been long time idle, I am not being killed but need to relogin.

Is this an issue with our office ISP? or could be a profile settings issue in EBS?
Please help how to resolve this disconnection issue.
Kind regards,
jc
