I have a domain registered with
namecheap and server instance is
aws ec2 (windows machine running node js) , cname record pointing to ec2 instance's public ip.
Now i want to configure ssl on it , I already have a Positive SSl(comodo) in my namecheap product list, which says Enter CSR.
However for some reasons I may need to change my ec2 instance, which inturn will change it's public ip, in that case will that CSR or ssl cert become invalid ?
If yes then is there any workaround ?
For generating csr i found this link
Sorry if it's something pretty basic but I am new to this
EDIT: If possible Plz point me to some good resources where I can understand all this
