Server whitelist issue

[00itsm00]

Hello there,

Installed it on server and it shows below error:
Request host is not whitelist enabled for this server. Please use the --host command-line flag to whitelist a specific host (recommended) or use --enable_host_checking to disable host checking. See the command-line flags help text for more information.

tried to look everywhere but not able to find how to whitelisting disable or to put in whitelist

found this command on a forum but i don't know here to put it.

dev_appserver.py /root/sympy_gamma/app.yaml --enable_host_checking=false

Please guide me how to get this issue resolved.

Thanks.
