Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

Welcome to the community @Phichie2

Your server is only sending the "leaf" certificate but it needs to send all the intermediates too. I saw from your server response headers you are using Apache version 2.4.46. With that version you should have lines something like:

SSLCertificateFile    (your path)/fullchain.pem
SSLCertificateKeyFile (your path)/privkey.pem

Your SSLCertificateFile right now is probably referring to cert.pem instead

You can check your certificate now and after the change using this

Updated to note specific Apache version
