NimbostratusGTM SSL Handshake to server failing
I am using GTM's to round-robin between 3 V Centre servers across our estate.
Connectivity and health checking is on port 9443.
Testing the monitor in our lab worked fine (11.6.0) no errors and pools green
In production we are seeing thew following errors (pools going offline):
SNMP_TRAP: Pool /Common/WF_VCS_POOL member (ip:port=10.x.x.x:9443) state change green --> red ( Monitor /Common/VSPHERE_9443_MONITOR from 10.x.x.x : connect: protocol mismatch search result false)
Production software: 11.3.0
Monitor configured as:
Send: GET /vsphere-client/ HTTP/1.0\r\n
Receive: vSphere Web Client
Alias port 9443.
All other settings default.
Any ideas?
Many thanks.

Most of the time, this could be related to configuration issue. e.g. the virtual server was assigned a https monitor but the configured service port was port 80 instead of port 443.

This could be the result of an SSL cipher or version mismatch. See this thread for a discussion: SSL handshake failure with monitor
