Hello, There is a bug at nginx it's serving wrong content and it's not ssl issue that most people has. 2 website both of them has ssl installed and working fine for the first time however after few minutes site1.com serving content of site2.com when i investigate the issue i found that it's related to cache once i empty folder /www/server/nginx/proxy_cache_dir the problem solved however as well few minutes and the problem back again so my solution for now it's to full disable reverse proxy cache by adding it like this or disable it from proxy conf :

I can Replciate the issue on 2 Servers same issue With Static Software and wordpress so it's not related to software.
My Current Version : 2.4.0 PRO / Sub apaanel
So The Problems are :
1 - Cache enabled even if i didn't setup it or allow it :
2 - Serving Wrong Content if cache are enabled
