Collabora Comunity Server will not load Documents

Hello everybody,

I have the Collabora Comunity Server running here on a Nextcloud 19.0.4 When updating from NC 18 to 19 and the first installation, the creation and opening of office documents works as it should. After the first update of the community server this is no longer the case. Libre Office is loaded in the browser but the document to be edited is not shown but only the menu bar of Libre Office. I have no approach to troubleshooting. Can anyone help me?

Thanks a lot

Hi @Schwanzlurch, did you check the log in the admin section of nextcloud? Thats the first place i would have a look.
