If I try to reach the server directly over IP and port (not over NginxProxyManager) I get this message: 

This software application is registered to a different server hostname.

thanks for your reply.

I will do some tests tonight and come back to you.

it's about 2-3 minutes ;-(

Hi again

The timeout in nginx is now longer than before. I do not get the error 504 anymore.

But still it takes such a long time to load a folder with 1GB and 314 pics. Are there any settings I could this make faster?

Thank you in advance.

Hi there

Thank you for the fast reply. So we can enclose the problem.

Do you know where and how to config the timeout period? This is a problem in nginx right?
