Despite I have followed all documentation and I have the “Nextcloud selftest” marked green I have log flooded continuously by this error
GuzzleHttp\Exception\ClientException: Client error:GET http://localhost/nextcloud/apps/richdocumentscode_arm64/proxy.php?req=/hosting/capabilities` resulted in a403 Forbiddenresponse: 403 ForbiddenForbidden (truncated…)`
It looks like this request is considered a security violation.
Is there some exception that needs to be added in firewall or some specific configuration to fix this, or it is a bug?
