On one of my servers (Plesk on Linode) I have several Joomla sites. Sometime in the past couple weeks we are no longer able to select (or upload) an intro or full article image to an article. It is happening on all J3 sites on this server (not on the J4 sites).
Specifically when you click the SELECT button next to the intro image entry box on the article's Images and Links tab, the normal pop-up/modal window appears however, the folder ad files areas are all empty. And the Cancel/Refresh/Insert buttons don't do anything.
This is obviously a server configuration issue in some way but have yet to figure out example where the issue might be.
The server logs for one of the domains from the point that we click the SELECT button to select an image (and the pop-up/modal opens) is listed below. Which seems to show that it is a problem with the server and specifically with nginx.
Additionally we are noticing problems the JCE Editor (nothing is displaying). And were getting similar nginx errors (connection refused).
Has anyone here run across this sort of problem and/or errors? We have several other similarly configured servers that are having no problems. And it appears that the problems are limited to Joomla. We have several other web systems running on different domains on the same server and none of them are having problems. Just the J3 sites are having issues.(All are running J3.10.11).
Any ideas or even thoughts of where to look would be welcome.
Here is the server logs from the point of the error happening (Domain and local IP addresses changed to protect the not-so-innocent server :-) )
