Error description

• When DataPower sends a request to a backend service and there is
  a proxy in the topology, the host name of the proxy is set as
  the value of the SNI-Host header instead of the hostname of the
  backend service
  

Local fix

• Work Around
  
  Configure the SNI host name in the SSL Client Profile.
  1. Set "Use custom SNI Hostname" to 'Yes'
  2. Then enter the desired host name in the "Custom SNI hostname"
  field.
  

Problem summary

• The TLS extension SNI hostname might incorrectly get set to the
  proxy hostname  when accessing a proxied HTTPS resource.
  

Problem conclusion

• Fix is available in 7.2.0.11, 7.5.0.5, 7.5.1.4 and 7.5.2.2
