i have vps on go daddy and i cant ping 162.125.8.8 what should i do ?
I see you're referring to an IP address that happens to belong to Dropbox. The Dropbox IP addresses can change though, so please use the relevant Dropbox host names. For example, for the Dropbox API, most endpoints are on api.dropboxapi.com and content.dropboxapi.com. Are you having trouble connecting to the Dropbox API via the hostnames?
If so, is there anything on the server's network connection that may be interfering with the calls to *.dropboxapi.com? E.g., any proxy, firewall, anti-virus, etc.? Is the server able to access the Internet otherwise?
