Collabro server Nextcloud AIO - using Built in ARM 64 instead

Hello, im using Nextcloud AIO and installed the Collabro image, wich you can choose, when you install it. Unfortenly, the WOPI needs a static IP, otherwise you have to update it every time, you dynamic IP changes. Thats why i want to install the App Collabro server ARM64, as a replacement, sio i dont have to update the Ip. But if i uninstall the Collabro server, via the Nextcloud AIO interface, then the ARM 64 built in server, then go to adminsettings, and choose that instett, i get a warning, that Nextcloud couldnt connect to the Collabro docker server:Failed to connect to the remote server: Could not find urlsrc for application/vnd.openxmlformats-officedocument.wordprocessingml.document in WOPI discovery response ( obviously). If i then try to open a document, or create one, i get this error: Didn’t find urlsrc for mimetype application/vnd.openxmlformats-officedocument.wordprocessingml.document in this WOPI discovery response:

Socket proxy error

Error: no_glibc

. Any ideas, how to solve this?
