[bitfolk] Networking? problem

Hi All, I have had a user complain they got no response from a website on my VPN. It appears that from about 9:07 until after 9:44 my front-end (nginx) could not talk to the back-end (php). It cleared before I became aware of the problem. I can find nothing in the logs, other than the failed reads, so I am at a loss to diagnose things. Environment - The O/S is Ubuntu 18.04 LTS. nginx is version 1.16.1 compiled to include a couple of extra modules...standard stuff plus... --with-pcre=../pcre-8.42 \ --with-zlib=../zlib-1.2.11 \ --add-module=../nchan-1.2.6 nginx talks to php7.2-fpm using fastcgi-pass to 127.0.0.1:9000. Any ideas gratefully received! Regards Ian -- Ian Hobson -- This email has been checked for viruses by AVG. https://www.avg.com
