Problem bei der Installation einer neuen Discourse-Instanz

[Falco]

Sie können versuchen, die MTU der Docker-Schnittstelle zu verringern:

Fresh install failing - gnutls_handshake() failed: Error in the pull function

Well it turns out the issue was in fact the MTU of the docker0 network adapter. I resolved the issue by changing the following line: ExecStart=/usr/bin/dockerd -H fd:// to ExecStart=/usr/bin/dockerd --mtu=1400 -H fd:// in my /lib/systemd/system/docker.service Thanks for trying to assist.
