We have a site deployed on crafter, when we access it directly with "IP:port" it works fine. But when we are accessing it with Nginx reverse proxy, it gives 500 for images and other api's.
Also it is not giving any error in nginx error.log
Request you to please help, we are stuck here.
There can be a multitude of reasons as to why you are seeing 500 code errors
As suggested in the comment, you need to increase the log verbosity to get more details about the error
Based on your nginx configuration, the error file can be /var/log/nginx/error.log or a different one.
Alternatively you can check the logs using journalctl depending on the service management system in place
It could potentially be a permission denied issue when accessing the static files so you need to make sure the user spawning the nginx processes has the correct access level
Please share the nginx configuration file and the permissions associated to the files to be served
