Greets, For some reason NGINX sometimes stops serving my tomcat pages and starts wanting to serve pages from .../nginx/html/. I don't get it. On Friday, at 13:39, I was happily browsing my XWiki site, as you can see from the NGINX access_log. Then from that log you see no activity until 10:31 this morning, at which time it no longer wants to redirect hits to port 8080 or to /xwiki, it just wants to serve from its own html/ subdir. When I come in this morning, When I go to hit the site NGINX shows me the placeholder page, .../nginx/html/index.html, which starts out "If you can see this page, ..." I can still hit my xwiki at :8080/xwiki. It has not been restarted, altho so what if it had? NGINX has not been restarted, and the config files (conf/nginx.conf, conf.d/tomcat.conf) have not changed. Anybody else seen this? Why did it change behavior, and doe it have anything to do with the "signal process started" messages? Thanks NGINX Access log, showing a few hits to xwiki at 13:39 on 05/05, then non-redirected hits at 10:31-10:41 AM on 05/08 ------------------ 10.13.107.52 - - [05/May/2017:13:39:39 -0700] "GET
