Hi. This (obscure) error means, that primary IP is chosen based on label selector, however given selector doesn't yields any usable IP address. Usable address must be free (unallocated) and must be within same datacenter location. You can use this link to configure detailed logging where you can check response from Hetzner cloud.
I seem to experience the same issue and am puzzled whats going on.
Background: we want to move our Jenkins instance to a new server. On the new server the Hetzner plugin does not want to function with the error printed in the leading post of this issue. On the existing instance, with seemingly the same config for the plugin it works fine.
When I look into the detailed Hetzner plugin log I see:

It seems the plugin does not attempt to create a server and then trips over the fact that there are no public IPs available.
The standard Jenkins log shows:

Any idea whats going on?
I think I found a hint. Looking at the config.xml
of the two instances I find the following difference:
Not working instance:
<primaryIp class="cloud.dnation.jenkins.plugins.hetzner.primaryip.ByLabelSelectorFailing">
<failIfError>true</failIfError>
<selector></selector>
</primaryIp>
Working instance:
<primaryIp class="cloud.dnation.jenkins.plugins.hetzner.primaryip.DefaultStrategy">
<failIfError>false</failIfError>
</primaryIp>
However in the GUI the config looks the same.
Another update. It turns out this setting did the trick. It is also visible in the GUI but under the advanced section of a server template. Not setting the "default strategy" as the default setting in new setups seems like a bug to me.
Hi @sandrinr, you are correct - good analysis. This might be result of incorrect migration of configuration around the time this feature was introduced.There is no fix possible other then re-create template from scratch. Issue will not repeat after template is modified I believe
OK, so if it's fixable from GUI, that's even better. Again, this is bug, but it was introduced by older version of plugin and it won't repeat with current version.
