Unbound can't write logs to file

I installed unbound 1.13.1 and I want to use it as a recursive resolver and log everything into a file. Unfortunately, unbound does not write into the file and I get the error: Feb 15 11:46:53 unbound[832702:0] error: Could not open logfile /etc/unbound/unbound.log: Permission denied The file's ownership has already been assigned to user unbound and the service has been restarted: 0 -rw-r--r-- 1 unbound unbound 0 Feb 15 10:17 unbound.log I also tried to create this file in multiple other directories like my home directory, under /var/sys/log/ etc. but the exact same error persists. And this is what the config file looks like: include-toplevel: "/etc/unbound/unbound.conf.d/*.conf" server: use-syslog: no chroot: "" username: "unbound" directory: "/etc/unbound/" logfile: "/etc/unbound/unbound.log" verbosity: 5 log-queries: yes log-replies: yes log-tag-queryreply: yes log-servfail: yes log-time-ascii: yes do-ip6: yes interface: 127.0.0.53 port: 53 prefetch: no root-hints: /usr/share/dns/root.hints harden-dnssec-stripped: yes Does anyone see what I am doing wrong regarding the log file?
