Nginx passenger - Images issues on 7.7

Greetings,

First of all my compliments on 7.7 version. It's really awesome.

Not sure if it's related to gitlab or more my server setup. I upgraded the Gitlab version and switched to nginx web server. Generally everything works fine, but I have issues with the uploaded images. This is how they are displayed in an issues list:

Here is the view issue page:

Anyhow, when I check uploaded file on websites - it's uploaded correctly.

Also, sometimes the system does not show all comments for the issue. You need to click Project link, press CTRL + F5, and then switch to issues list again to see them.

Could you please assist on this. Here is the information that might help for debug:
