Error: Issuer's public key doesn't correspond to its private key

Dear experts,

I'm trying to enable access for Web Client on manually installed NAV 2017 on Microsoft Azure. The time when I tried to create certificate using the makecert.exe utility, I've found an error. At part of makecert -sk NavServiceCert8 -iv RootNavServiceCA8.pvk -n "CN=NavServiceCert8" -ic RootNavServiceCA8.cer -sr localmachine -ss my -sky exchange -pe NavServiceCert8.cer, once I put the password system prompted Error: Issuer's public key doesn't correspond to its private key. Please advice.

Thanks in advance.
