Hello all,

I'm new in iRedMail and like to replace zimbra systems with it.
The system is running on a 4Core,8GB vServer. Only Nextcloud is also running on the same box. At the moment I only have two active mail users and one active nextcloud user.

In the morning I start a browser and enter the SOGo-Login page and see a page without any css/images (you can see it in the attached screenshot). Pressing F5 (refresh) a few times will bring the "right" content. After logging in, and switching to calendar or contacts or email I only get a blank page. Sometimes it works, sometimes not.
After restarting the server (or sogo and nginx) the issue seems to be gone for a while.

It feels like a caching problem on the server side.

Can someone point me to the right direction how to eliminate this issue? Which logs can I use to find any helpful information's?
