F5 Big-Ip upgraded to 11.1, "Open SSL error - error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure" and many other errors

with -IK opation, works i am run out of ideas. can you try to capture packet? is there anything suspicious?

 

 

steps could be like this.

 

1/ remove https monitor from pool member

 

2/ start tcpdump

 

e.g.

 

tcpdump -nni 0.0:nnn -s0 -w /var/tmp/output.pcap host x.x.x.x and host 192.168.32.129 and port 443

 

x.x.x.x is non-floating selfip

 

 

3/ assign https monitor to pool member

 

4/ stop tcpdump (^c)
