Yes, together with height: 100% as well the image is there. Thanks!

Thanks! I changed the line and working fine now.

@wishmaster270 I did some research. Somehow the network wasn’t right anymore. The cam got a different ip-address, so it was rebooted somehow and using DHCP got a different address. Now it is set to the same address. I did replace the first switch to which the NAS and the cam are connected. For the cam I use a repeater that uses the electrical net to connect to my backbone. A cable would have been difficult. After a reset of all that components, the cam was reconnected and all is working again.
