Bug Details

Description

Symptom

Currently, HTTP client only uses the IPv4 address if it receives the source interface in the transaction and reports an error for IPv6/FQDN URLs if only ipv6 address is configured on the source interface.

Conditions

We will see this issue only if the application passes the source interface to the http client.

Workaround

unconfigure source interface configured under call-home configuration.
