matrix-synapse.service: Failed with result 'exit-code'

[tomnick]

Hello everybody,

I did upgrade my matrix synapse server via ansible. Before it was running fine. Now, I am getting the following error and the server does not start:

matrix-synapse.service: Failed with result 'exit-code
Failed to start matrix-synapse.service - Synapse server

my systemctl status matrix-synapse.service:

Does anybody have any idea what I might be missing here? Thanks for some hints.
