Today I found myself restarting a docker stack, which is running Nginx Proxy on a HA stack running (3) Linux VM’s. After restarting the stack, I noticed that one of my WordPress installs wanted to keep redirecting to the install.php file for WordPress.
Typically, you would think this is a wp-config.php or .htaccess file problem, but after digging around for a little bit, i realized that the nginx-gen container had not restarted with the rest of the containers in the jwilder stack.
Simply start up the nginx-gen container, and WordPress will now work properly.
