NginX
After the SSL certificate is generated by the issuing authority, the files are sent to the administration address.
Sometimes during the installation of the SSL certificate the concatenation command corrupts the certificate code.
In this situation open the file with the SSL certificate in a text editor and check that the following lines are on different rows:
-----END CERTIFICATE----- -----BEGIN CERTIFICATE-----
Make sure you have 5 "-" signs in the header and footer of the file.
The NginX configuration file can be reloaded running the following commands:
nginx -s reload
service nginx reloadCheck the website again using the HTTPS protocol.
Apache:
The same situation can also occur on Apache servers. Verify that the file concatenation was done correctly, then execute the command:
ervice apache2 reload
