Problem with SSL - CentOS 7

#1
I have installed 1.4.13 on CentOS 7 with SSL. It's worked.
Few day ago, my website can not run with https domain but still work with ip address. Timeout when used https.
I checked lsws status with /usr/local/lsws/bin/lswsctrl status, it seem Litespeed is running (litespeed is running with PID xxx.).
Checked with systemctl status lsws seem like loaded and active. But https can not run.
If i restart lsws service, website can run over https. But after about 15 mins, the problem is come back.
Please help me.
