WEBSERVICES becomes inaccessible when failover
Hi experts,
I would like to get some help with this issue we've been trying to resolve that even F5 TAC is unable to find the root cause until now for several months already.
We have an F5 Big-IP which runs LTM and ASM. Each virtual server is assigned with a WAF policy.
Our big problem is, whenever we failover the active unit to standby unit all websites becomes inaccessible for more than an hour. Some comes up in 30 mins, most are within an hour and some after nearly 2 hours. It is also the same symptom when we fail back the active unit.
Anyone can advise what issue we could be facing here?
We are using version 12.1.3.3 Build 0.0.1 Point release 3
Thanks a lot in advance,
