LTM Nonterminating HTTPS VIP Not Working

Experiencing intermitten non rendering https VIP issues. We have created multiple nonterminating https VIPs that intermittenly render https requests. The browser will spin until it returns a destination unreachable. While this is happening each server is up in the pool and successful renders https requests to a browser.

 

 

Troubleshooting the issue we replaced the primary F5 with a new unit and the the issue stopped happening. In testing failover this week we made the standby unit active and everything worked fine but when we returned the primary to active it could not render https request. After a reboot the primary still would not render the HTTPS VIPs. Then we forced the standby to active and the VIPs rendered successfully. We then forced the primary to active and the VIPs render successfully again.

snat automap

 

pool air_app

 

destination 123.41.20:https

Any and all help is appreciated,
