i have a Problem with a couple of multiple Raspberry Pi Devices with Screenly OSE installed.
Two Weeks ago they stopped displaying Websites from IServ which is a Software in the Education Sector.
In IServ there is a Module which provides URLs which then contains specific Timetables/Content for the pupils.
For example this one:
I can access the URL from other PCs without Problems and other Websites work also without Problems with the Screenly PIs.
On the Screenly-Displays there is just a white Screen.
Can anyone help me?
