We haver some servers running with letsencrypt and allways works fine.
But since yesterday, one of them have some random errors about SSL certificate.
I renewed it yesterday (and today too) and its valid until September. All works, I can navigate thought web app, but sometimes (random pages) it show an error and cannot load the page. Go back and go to the same link and works fine.
It’s not always at same page, and I cannot locate any error log about it.
Its an ubuntu 16.04 server with php7.1-fpm and Nginx , only one site by server, but it’s the same as other 12 sites
