Cirrus
MVPCheck the port-lockdown settings on the big-iq self-ip and ping and telnet to the vmware vcenter and if needed do tcpdump on the F5 and maybe on the vcenter. The standard stuff, you need to do basic network investigation as the error seems self explanatory 🙂
CirrusI did the network inspection on very first day, everything is fine from layer 2-4. I can ping and telnet the VMware IP from Big-Iq.
From pcap, initially I found CA issue which was fixed, now even though in capture I could see that authentication is fine as after server hello encrypted messages are exchanged.
Still, in big-iq vm creation task it's showing can't resolve (VMware IP which is addiin cloud environment), I added the IP in etc/host file, still the same issue.
MVPIf checked the network connection and DNS is correctly setup on the F5 BIG-IQ and maybe looked at the bug tracker ,upload qkview to ihealth and see and check your big-iq release notes https://support.f5.com/csp/bug-tracker / https://techdocs.f5.com/en-us/bigiq-8-2-0/release-notes-big-iq_1/chapter-title-rel-note-fixes-known-issues_1.html as if your BIG-IQ is not the latest version it could be a solved bug, then you may try support.
