System: CentOS Linux release 7.6.1810 with Apache2
Have a running and working nextcloud 15.0.7
Have installed CODE 14.0.3 localliy without docker according to https://www.collaboraoffice.com/code/linux-packages/; loowsd service is running fine; certificate is working proper
Have configured an Apache proxy according to https://nextcloud.com/collaboraonline/
I can reach https://[mydomain]/hosting/discovery and receive the xml
I can reach and interact with https://[mydomain]/loleaflet/dist/admin/admin.html
I have installed and configered the Collabora Nextcloud App (only entered https://[mydomain]:9980/)
Problem: When I navigate to any stored document or create a new one, it does not open for edit, it simply shows a circle on opening or times out on opening after creation.
Anyone an idea, what the problem could be?
