Please need your help. I need to update my SSL Certificate but, Xibo can’t recognize it, how can i install this certificate?

So the code and which files you need in which specific way.

SSLCertificateKeyFile "/srv/xibo-cms/SSL/companykeyfile-decrypted.key"
SSLCertificateChainFile "/srv/xibo-cms/SSL/Sectigo_RSA_Domain_Validation_Secure_Server_CA.crt"
