Hi @durgadeep,
From the certificate, it looks like you have server.dc1.consul in SAN, and I don’t expect to see the error that @midhunkonduru posted. Could you verify again?
However, I can see that you only have TLS Web Client Authentication for the Extended Key Usage, which would give you errors similar to what is mentioned in this post (Consul Client join consul servers cluster | certificate error - #2 by maxb)
