Connection to server lost after fresh install 11.0.2

Hi we installed a fresh version of 11.0.2 nextcloud on a virtual server. The Web Interface is pretty slow, some icons are not shown and frequently the error message “connection to server lost” occurs.

Any idea what is the problem here? Tried with safari and chrome.

You didn’t provide any information, so no idea. What OS? What webserver? How is your server configured? What’s in logs?

Ubuntu 16.04 LTS, 4GB RAM, Apache2, nothing special in the logs. Just wondering if we are the only one with this issue?

I have the same problem on a linux server 2.6.32, I’m not sure for the web server but i think it’s a Apache2. Php version 5.6.30

The folders page is empty and I have the message “connection to server lost”.
It’s a fresh installation, nothing configured or created.

There is an error in logs : InvalidArgumentException: The given object name is invalid
