I think the server certs you created are lacking one or more extensions, 
I'm just not entirely sure which ones.

You are answering Y, <blank>, Y here right, for: CA certificate, no 
length, critical?

I'd also add: --keyUsage 
digitalSignature,nonRepudiation,certSigning,critical

I'd add in: --extKeyUsage serverAuth,clientAuth --keyUsage 
digitalSignature,nonRepudiation,keyEncipherment,dataEncipherment

You pass in a serial # elsewhere, you may want -m 2 for consistency.

No need to re-create the CA certificate.
