OCSP responder timed out

[wecreatedigital]

Hi there

I've noticed many lines like the below in my nginx-sp error logs. Is this anything to be concerned with?

2018/09/27 10:38:51 [error] 1043#0: OCSP responder timed out (110: Connection timed out) while requesting certificate status, responder: ocsp.int-x3.letsencrypt.org, peer: 2.21.67.65:80, certificate: "/etc/letsencrypt/live/subdomain.example.com/fullchain.pem"

SSL certificates do appear to be renewing without any issues on Ubuntu 18.04. We had an issue this morning where I had to restart nginx-sp but I don't think this error is related.

Thanks

Dean
