Base: Debian 9
Docker Packages: docker.io 18.06
Image: Nextcloud from Docker Hub
based on the default install on my netbook everything works as expected. I can connect to my Nextcloud images from every machine on my network.
The second install on my desktop uses macvtap interfaces because i have a KVM / Qemu/ libvirt configuration. On this machine everything works ONLY with the localhost interface.
If i try to connect to my desktop Nextcloud container from local desktop with http://localhost:8080 everything works. If i try to connect from another ip address no connection is possible and no error messages apperars - only a blank screen.
Looking with wireshark sniffer tell me that the container network interface recognise the network request but the internal nextcloud http daemon reject the connection with a http 500 error message. Say all and nothing …
Any hints for me?
Thanks in advance!
