F5 APM RDP Connectivity issue user logged out spontaneously

Without seeing any logs or errors my first guess would be are the user's letting their devices go to sleep. This will disconnect APM sessions, second thing I would look at is the time on local machine versus what is on the server.

Are there any errors on the BIG-IP or local machine that you can find and show us?

Hi Brad, thanks for your answer.

Unfortunately I don't have any error messages which point in that direction. Within the apm report says the user session is deleted because of user logout.

The time settings on the local workstation where APM access is started could be an issue? The time settings of the APM and Windows server are the same.

I just bring up time because I haven't seen it first hand on APM cause issues but I've seen it cause authentication issues. An example, years ago I had an issue where certain users could occasionally connect to Windows messenger. Weeks later it had to do with Kerberos and the time on the machines versus what was on the servers sigh That was a bad month lol. If the time was more than 5 minutes off the authentication tokens would expire and deny access. Also I wouldn't trust an end user to set a clock =)

My guess is there is something going on with these users computer in regards to connectivity.

Do you have a laptop setup where you could attempt to duplicate the issue?

Hi Brad, the problem is we can't duplicate the problem when we want to. We have laptops but the issue isn't always there so we're depending on user input about these problems.

In progress of this issue we're going to plan an upgrade to version 11.5.1 and see if the problems still occur.

It seems that after the upgrade this APM environment is much more stable.
