The trust relationship between two Shrine nodes could not be established.
This problem can happen for one of several reasons:
Clock drift between the site that the query originated at and the receiving site. Check your server's datetime. Make sure it's clock is properly synched using ntpd.
The certificate offered up by the querying site is not trusted by the adapter due to a configuration problem.
If using CA trust model: Ensure that the CA-signed version of the originating site's certificate was imported properly. Ensure that the Adapter properly trusts the CA cert.
