Content library woes (again)

**edit:**

tl/dr: Doesn't seem to work with IPv6 host < - > vcsa communication.

For some reason I seem to be able to break the content library service in many different ways without knowingly doing it in the first place. This one has me stumped at the minute though.

I have a content library backed by a VMFS6 datastore, which whenever I try an perform an operation on it I'm treated to a failed task and the following error:

`A specified parameter was not correct: spec.source.cnxSpec.host`

I'd changed the DNS names of my hosts last week and I'm somehow guessing that it might be related, I'm IPv4/6 dual stacked throughout which also may not be helping matters but it should work as far as I'm aware. I can see in vpxd.log that the cnxSpec object gets generated with the seemingly correct IP address (4 or 6).

I'd love to just open a ticket for this which would be nice and easy but unfortunately this is just my homelab so I'm hoping someone else in the community may have experienced this or know more about the inner workings that may be able to point in the right direction. Everything else vCenter wise seems to be working.

PS. This is 6.5 U1g. Hosts match and it doesn't matter which one the VM is on it always gives the same error.
