MySQL cannot get private key from a readable folder

[Tracer DS]

Hi. Im having a serious issue with mysql.
I want to enable ssl connection but I'm having some issues while doing so.
As you can see (image 1) myqsl cannot read private key from /server/pkey.pem file.
HOWEVER when I run a shell script /test.sh (permissions: 777), it prints the content just fine (image 2).

HOWEVER when I move the /server/pkey.pem file to /etc/mysql/pkey.pem, mysql reads the file just fine.

So... what the heck is going on here?
