Trouble with sending logs from filebeat to elasticsearch

Hi Mark, thanks for your reply!

Sorry for such a long answer, it was night here :sweat_smile:

I don't really know what logs you are waiting for, so I will put here everything that Filebeat ouputs :smiley:
in /var/log/filebeat/filebeat and /var/log/filebeat/filebeat.1 there are the same two strings:

2021-11-19T12:44:50.158Z        INFO    instance/beat.go:665    Home path: [/usr/share/filebeat] Config path: [/etc/filebeat] Data path: [/var/lib/filebeat] Logs path: [/var/log/filebeat]
2021-11-19T12:44:50.160Z        INFO    instance/beat.go:673    Beat ID: 4559f684-2e7f-4ae2-b28c-0c2884bb4218

systemctl status filebeat outputs:

When I also started filebeat setup -e there were a lot of messages about dashboards set up in Kibana, but I couldn't see anything about logs.
