Hello @Robbybaehaqi8,

Do on the server >nslookup www.cisco.corp

Does an IP is returned ?

hmm am not sure but is the DNS set up correctly for internal domains like that? sometimes our team had issues with .corp URLs not resolving unless the DNS server knew about them. also just to confirm, are you testing this inside the company network or from outside?

what does www.cisco.com return?

www.cisco.corp is not an active, and I don't think .corp domain names are valid overall.
