403 errors after moving

[thommierother]

When moving files, I frequently see the following pattern in the log:

{"reqId":"p1fxfIXNyd9SvUugiiEv","level":2,"time":"November 18, 2018 15:00:02","remoteAddr":"","user":"--","app":"filesystem","method":"--","url":"--","message":"Storage wrapper 'oc_readonly' was not registered via the 'OC_Filesystem - preSetup' hook which could cause potential problems."}
{"reqId":"p1fxfIXNyd9SvUugiiEv","level":3,"time":"November 18, 2018 15:00:02","remoteAddr":"","user":"--","app":"files","method":"--","url":"--","message":"Exception: {\"Exception\":\"OC\\\\ForbiddenException\",\"Message\":\"\",\"Code\":0,\"Trace\":\"#0 \\\/var\\\/www\\\/owncloud\\\/lib\\\/private\\\/Files\\\/Utils\\\/Scanner.php(139): OC\\\\Files\\\\Utils\\\\Scanner->shouldScan(Object(OC\\\\Files\\\\Mount\\\\MountPoint))\\n#1 \\\/var\\\/www\\\/owncloud\\\/apps\\\/files\\\/lib\\\/BackgroundJob\\\/ScanFiles.php(87): OC\\\\Files\\\\Utils\\\\Scanner->backgroundScan('')\\n#2 \\\/var\\\/www\\\/owncloud\\\/apps\\\/files\\\/lib\\\/BackgroundJob\\\/ScanFiles.php(111): OCA\\\\Files\\\\BackgroundJob\\\\ScanFiles->runScanner(Object(OC\\\\User\\\\User))\\n#3 \\\/var\\\/www\\\/owncloud\\\/lib\\\/private\\\/BackgroundJob\\\/Job.php(57): OCA\\\\Files\\\\BackgroundJob\\\\ScanFiles->run(NULL)\\n#4 \\\/var\\\/www\\\/owncloud\\\/lib\\\/private\\\/BackgroundJob\\\/TimedJob.php(53): OC\\\\BackgroundJob\\\\Job->execute(Object(OC\\\\BackgroundJob\\\\JobList), Object(OC\\\\Log))\\n#5 \\\/var\\\/www\\\/owncloud\\\/cron.php(120): OC\\\\BackgroundJob\\\\TimedJob->execute(Object(OC\\\\BackgroundJob\\\\JobList), Object(OC\\\\Log))\\n#6 {main}\",\"File\":\"\\\/var\\\/www\\\/owncloud\\\/lib\\\/private\\\/Files\\\/Utils\\\/Scanner.php\",\"Line\":192}"}

The client shows a 403 forbidden from the server but returns to "green" state shortly later. An idea about the reason or possible workarounds? Note: the server uses user key encryption

GitMate.io thinks the contributor most likely able to help you is @ownclouders.

Possibly related issues are #12809 (Syncevolution stopps due to 403 error Access denied), #28840 (-Error-), #26902 (error), and #25681 (Strange errors about Scanner.php and Propagator.php).

seems the logs are unrelated ? they look like they were triggered from cron.

Maybe some of your external storages or received federated shares have some blocked/forbidden entries ? Maybe the real error is on the target server.

I have federation on this system with two other instances, both nextcloud 13, so it is possible that the root cause comes from the federation partner. Closing issue because the error disappears and is not permanent
