An LTM Specialist is reconfiguring a virtual server to redirect all clients to HTTPS. Testing reveals that the redirect is functioning incorrectly. As part of the troubleshooting process, the LTM Specialist performs a packet capture.
What is the issue?
A device group is made up of four members: LTM-A, LTM-B, LTM-C, and LTM-D. An LTM Specialist makes a configuration change on LTM-B. Later, a different LTM Specialist notices a "changes pending" message on all devices. When logged into LTM-D, the LTM Specialist attempts to config-sync to the device group. The sync operation fails.
Why is the LTM Specialist on LTM-D unable to synchronize the configuration to the group?

An LTM Specialist configures an HTTP monitor as follows:
ltm monitor http stats_http_monitor {
defaults-from http
destination *:*
interval 5
recv "Health check: OK"
send "GET /stats/stats.html HTTP/1.1\\r\\nHost: www.example.com\\r\\nAccept-EncodinG. gzip, deflate\\r\\nConnection: close\\r\\n\\r\\n"
time-until-up 0
timeout 16
}
The monitor is marking all nodes as down. A trace of the HTTP conversation shows the following:
GET /stats/stats.html HTTP/1.1
Host: www.example.com
Accept-EncodinG. gzip, deflate
Connection: close
HTTP/1.1 401 Authorization Required
