VUM VCSA 6.5 Can't scan host

[PRimmer_London]

VUM VCSA 6.5 can update other hosts, but not 1 particular cluster. On this cluster I can scan the hosts for updates just not patches and extensions

Firewall ports look good from ESXi to VCSA

nc -zv "XXX" 9084

Connection to XXX 9084 port [tcp/*] succeeded!

nc -zv "XXX" 80

Connection to XXX 80 port [tcp/http] succeeded!

Scratch space has 4GB free

esxupdate.log from ESXi shows

2018-08-22T15:01:17Z esxupdate: 25663422: esxupdate: ERROR: An esxupdate error exception was caught:

Check TCP 902 from vCSA/VUM to the management vmkernel of these ESXi hosts. This presents like a network-related failure.

Connects fine to port 902 of the IP address of the ESXi host from VCSA

curl -v telnet://XXX:902

* Rebuilt URL to: telnet://XXXX:902/

*   Trying XXXX...

* Connected to XXXX (XXXXX) port 902 (#0)
