I ‘ve got the same problem like in this question: SSL Error on Port 443, Page is not showing and resulting in error 404
I’m trying to create a facebook application, but I have problems and I keep getting the same error as that person:
Error 404
The server can not find the requested page:
–url– (port 443)
Please forward this error screen to –url–‘s WebMaster.
I already created through the SSL/TLS Manager a Key, CSR and CRT for the domain that I’m using for the application, but I still cannot get to the index.php through https, while through http is all fine. There is no activate SSL button or anything like this, so I’m a bit lost -using cpanel for the first time-
Help?
This is almost certainly a configuration problem with your web server not serving the right content on port 443, that error message is definitely from your web server’s side and not from Facebook’s API
