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. Sorry if this is already discussed I just now koined the mailing list and will look thru the archives now. 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
