Port 443 is not accessible to the Operator user role in vCenter Server 8.0.3x

Products

• VMware vCenter Server
• VMware vCenter Server 8.0

Issue/Introduction

The created user will not be able to access port 443 in vCenter Server 8.0.3x and later versions (including VCF 9.0), but will be able to access ports 80 and 22.
When accessing port 443 with the openssl command, the following error will occur:

test [ ~ ]$ openssl s_client -connect 127.0.0.1:443 < /dev/null
            C041756B937F0000:error:8000006F:system library:BIO_connect:Connection refused:crypto/bio/bio_sock2.c:114:calling connect()
            C041756B937F0000:error:10000067:BIO routines:BIO_connect:connect error:crypto/bio/bio_sock2.c:116:
            connect:errno=111
test [ ~ ]$                         
test [ ~ ]$ nc -vz 127.0.0.1 443
            nc: core.c:372: core_tcp_connect: Assertion `ret == 0' failed.
            Aborted (core dumped)

Environment

vCenter Server 8.0.3x
VCF 9.0

Cause

This is expected behavior in vCenter Server 8.0.3x and later.

Resolution

To work around this issue, try the following:

1) Run as the root user

Port 443 can be accessed by the root user.

Note: Alternatively, you can add a firewall using the iptables command, but this method is not supported.
