Can't re-add deleted host

I'm getting an invalid xml-rpc error:

Hi,

Please add essential information so we can help… How could we guess your XO(A) version? XCP-ng? XenServer?

If you want to get free support, you need to make a minimal amount of effort, of if you don't want to, get pro support then

[Danp]

Searching the forum I was able to locate a few similar issues. In both cases (first, second), there was an IP address conflict.

@olivierlambert @olivierlambert Merci, Olivier.

XenServer 7.0.0 (yes, I'll ask you about upgrading to XCP-ng one of these days real soon).

XOA is current.

@Danp Thanks, but not the case here...

So you are sure you are connecting to 216.252.162.94 in Xen Orchestra?

[qnetter]

@olivierlambert Um,... backs away shyly...

@qnetter said in Can't re-add deleted host:

There were 13 failed login attempts since the last successful login.

Maybe you're using the wrong password is XO(A)?

[qnetter]

@Danp no, we're a hack target...

[olivierlambert]

I would suggest to NOT expose the host directly on the outside. Especially such an old version with a lot of security issues.
