SSL Do Handshake Failed Crit Error

I have an ‘https’ website running. Everything works just fine, but looked through the /var/log/nginx/error.log and found out this odd thing - HERE. The ssl and everything works fine but the same subset IPs cause the following errors. Is someone trying to exploit site ? Should I worry about it? Do/Can I have to do something to prevent this happening?
