forced to provide RSA 2FA creds TWICE when load balancing via F5

[KyleCompassion]

I'm testing out load balancing via an F5 (not with an iApp, just super basic F5 config) and it's working. but I am finding that when i first connect with my client i have to provide 2FA, then i get a list of VM's, then when i select a VM to connect to i get prompted for 2FA credentials a second time. i also have to wait for the passcode to change before inputting it on this second prompt, otherwise i get Access Denied. Has anyone seen this or know how to fix it? i googled around and found nothing in F5 nor View documents. once i provide the second credentials, i can connect just fine.

It was caused by my lack of experience with F5's. I configured the pool to use Source Address Affinity for session persistence and the issue is gone. I suspect the F5 was routing my initial connection to CS1, then i provided RSA creds, then when i picked a VM the F5 was sending that traffic to CS2, which requested my RSA creds again. Now, as i understand session persistence, everything gets routed through whatever server the F5 initially routes me to.
