SSL Server’s certificate chain incomplete?

Does your SSLLABS report say ‘This server’s certificate chain is incomplete. Grade capped to B’?

Simple fix:

Concatenate the certificate file with the Intermediate CA.

Open your Certificate file and Intermediate CA in a text editor, copy all of the Intermediate CA file and paste it after the end certificate section.


Leaving just the Certificate and the Intermediate Certificate in the file.

Restart your web server and retest in SSLLABS.
