Not sure what is happening, but a website I am testing with, https://saxofoonkwintet.nl, gives the strange behavior that +50% of the time the server certificate is being loaded in stead of the website certificate, this gives an ERR_CERT_COMMON_NAME_INVALID. I did an update of Apache and Let's Encrypt yesterday morning, not sure if that is part of the problem. On the server are multiple websites still working correctly with Let's Encrypt ssl. Refreshing https://www.digicert.com/help/ gives different certificates.
