<fetch> library, and the Texis Monitor
schedule/web servers, can verify peer (remote server or client)
certificates. The Vortex
<urlcp sslverifyserver> setting
and the Texis Monitor schedule/web servers' SSL Verify Client
settings control this verification; they are normally "
on", peer certificates are verified: if the
verification fails, the SSL connection is terminated with a "Cannot verify certificate from host
at depth N" error. The reason can vary, as detailed in the
error listings later.
