Hi Sven, If you don't need REST API, you can temporarely disable it by commenting out lines with "api" in file /etc/koha/plack.psgi and reloading koha service.
Then try to investigate what is going on, from the log record it looks like you are not able to access url http://json-schema.org/draft-04/schema. Try to access it through wget or curl and investigate what is going on.
