I configured an IDM loopback driver that worked normally for a while,
but now it doesn't do anything when I initiate the job trigger.

NDSTRACE shows this:
New TLS connection 0x818c670 from, monitor =
0x27162700, index = 11
Monitor 0x27162700 initiating TLS handshake on connection 0x818c670
DoTLSHandshake on connection 0x818c670
TLS accept failure 1 on connection 0x818c670, setting err = -5875. Error
error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol
TLS handshake failed on connection 0x818c670, err = -5875
Server closing connection 0x818c670, socket error = -5875
Connection 0x818c670 closed

When I use the same authentication credentials in Apache Directory
Studio, it connects fine. What should I check?
