SLL not working for multiple virtual services

Gloo Edge Version

1.9.x

Kubernetes Version

1.20.x

Describe the bug

Hi I have two virtual services say one for domain a.example.com and another for b.example.com. When i add sslConfig for one it works completely fine. But when i add it for both am not able to access my service i get

curl: (35) LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to a.example.com:443

  sslConfig:
    secretRef:
      name: secret-name
      namespace: gloo-system

Using the same sslConfig for both virtual services. Does anyone have any idea what could be the issue here. I tried adding sniDomains with values a.example.com in one and b.example.com in the second one, but error is shown. When i remove sslConfig from one virtual service it works again.

Steps to reproduce the bug

I am using the same certificate for both my virtual services

my virtualservices
apiVersion: gateway.solo.io/v1
kind: VirtualService
metadata:
  name: name_1
  namespace: gloo-system
spec:
  sslConfig:
    secretRef:
      name: cert-name
      namespace: gloo-system
    sniDomains:
    - a.example.com
  virtualHost:
    domains:
      - a.example.com
    routes:
      - matchers:
         - prefix: /path
        routeAction:
          single:
            upstream:
              name: upstream_name_1
              namespace: gloo-system

apiVersion: gateway.solo.io/v1
kind: VirtualService
metadata:
  name: name_2
  namespace: gloo-system
spec:
  sslConfig:
    secretRef:
      name: cert-name
      namespace: gloo-system
    sniDomains:
    - b.example.com
  virtualHost:
    domains:
      - 'b.example.com'
    routes:
      - matchers:
         - prefix: /
        routeAction:
          single:
            upstream:
              name: upstream_name_2
              namespace: gloo-system
        options:
          autoHostRewrite: true

Expected Behavior

I should be able to access my services across https in both virtual services.

Additional Context

Output of glooctl check

Could be possibly relate to this https://github.com/solo-io/gloo/issues/2534 but i cant seem to find a workaround
