In the case of missing fs.cgi: your file server is not able to properly resolve your main server's DNS name
In the case of missing api.cgi: your main server is not able to properly resolve your file server's DNS name
Q: I logged into corresponding server with root SSH and checked by running 'ping <domain_name>'.
To my surprise, I have found that corresponding domain name is getting resolved to a completely different IP which I don't know at all!
But on my home machine everything resolves correctly.
How could I fix that?
A: You can pin a specific domain name to a specific IP by adding a corresponding record into your server's /etc/hosts file.
If you're not sure about editing /etc/hosts file, please report this case to your system administrator (if you have any) or hoster (if you don't have any or if you're a system administrator of this server).
