Nginx SSL Errors

My error log gets about 100 of these errors every day.

I'm using Nginx 1.19.6 - OpenSSL 1.1.1i

ssl_protocols TLSv1.2 TLSv1.3;

ssl_session_cache shared:SSL:20m;
ssl_session_timeout 2h;

ssl_stapling on;
ssl_stapling_verify on;
resolver 127.0.0.1;
resolver_timeout 5s;

Any idea what I can do to fix this?
