Ḥey @balaji.bandi Thanks for the quick responce however the guide yo provided is for creating New Certificate and it is self sign i want to upload my server genrated Certificate in FCM also please guide how to disable TLS1.1 in FCM

The process same here: the device generates CSR and you sign and uploading,

If you have a CSR and a combined certificate, you use the same guide and understand the process correctly.

Cisco has good documentation Look configuration guide for TLS :
