Hello,
I am using letsencrypt cert and key and do not want to restart kamailio every 3 months to load new ones.
I know that there is: kamcmd tls.reload method but it has an error for me.
error: 500 - Error while fixing TLS configuration (consult server log)
I am checking the logs and see:

Any advice ?
It's interesting that there are not any errors in case I restart kamailio. I can make TLS calls without problems.
deb 12.5
version: kamailio 5.7.4 (x86_64/linux)
