It looks like tou have 700 for root user on th cert directory and are
running kamailio as kamailio not route, which is correct, So can the
kamailio user read the cert directory?

Hello Ben,
Thank you for your reply. When I was installing Kamailio, I followed this:
groupadd -g 5000 kamailio
useradd -u 5000 -g 5000 -d /var/run/kamailio -M -s /bin/false kamailio
I am simply starting Kamailio like: systemctl start kamailio.service
Please find the below output for the command that you shared with me:
# kamailio -u kamailio -g kamailio -m 64 -M 16
Listening on

Thank you.

Hello Richard,
Thank you for your reply. If you noticed the steps that I used to
generate certificates, I had already given 700 permission to the
"certs" directory.
1.
mkdir -p /usr/local/etc/kamailio/certs
2.
cd /usr/local/etc/kamailio/certs
3.
chmod 700 /usr/local/etc/kamailio/certs
[root@rtpengine kamailio]# pwd
/usr/local/etc/kamailio
[root@rtpengine kamailio]#
[root@rtpengine kamailio]# ls -ll
drwx------ 2 root root 150 Oct 22 17:48 certs
[root@rtpengine kamailio]# ls -ll certs/
-rw-r--r-- 1 root root 1992 Oct 22 17:48 ca-cert.pem
-rw-r--r-- 1 root root 41 Oct 22 17:48 ca-cert.srl
-rw------- 1 root root 3243 Oct 22 17:48 ca-key.pem
-rw-r--r-- 1 root root0 Oct 22 17:48 crl.pem
-rw-r--r-- 1 root root 1870 Oct 22 17:48 kamailio-cert.pem
-rw------- 1 root root 3243 Oct 22 17:48 kamailio-key.pem
-rw-r--r-- 1 root root 1675 Oct 22 17:48 kamailio-req.pem
Please advise me, is there any other part that I missed? Thank you
in advance.
Best Regards,
Chandramouli.

from the error it looks like a permissions problem probably

Hello,
Please find my server environment below:
Operating System: RockyLinux 8.x and RHEL 8.x

I have generated SSL certificates using OpenSSL. After
configuring Kamailio, I am unable to start Kamailio. Please
find the steps that I used to generate certificates along
