hi Reqbaln ,

  I don't have experience with this setup, but have you taken a tcpdump on the BIG-IP to capture the transaction? You can enable some flags in tcpdump to allow for the tls keys to be included in the capture so it's easily decrypted in wireshark. I wrote a python script to actually take the capture, download it, and decrypt it for you for these situations.

On the solution info, do you have a confirmed working monitor with the nginx ingress as a pool member, and do you get successful feedback when running this from the BIG-IP command line?
