  • Not really to worry about. The error is logged by IIS and is caused by a error in the PKI encryption process with third party browsers.

    Check for more info.

    Fatal Error 46 is caused by Mozilla Firefox

  • most of the times I see schannel events can be tracked back to certificate issues. In case of it happens on HUB server i suspect it has something to do with SMTP TLS.

       If SMTP TLS issue why its not coming in other Hubcas server, error coming only in one server..

  • If its only on one CAS/HUB then either clients is only accessing this server or this server is only accessing another system that cause this events.

    You can turn on CAPI2 logging to get more clues.
    Open Eventviewer, goto application and services logs/Microsoft/windows/CAPI2, right click on operational and select enable log. This will get you info about whats going on. Dont forget to disable CAPI2 logging when done.
