Hi,

very likely related to #5036 where some workarounds like using a cronjob to rescan the external storage where posted.

Edit
Another ref to a duplicate reported issue: #11797

[jvillafanez]

I don't think is related to #5036 because that issue affects all external storages (or at least it did). This issue affects only to FTP storage. Other storages get the new file correctly after reloading the page in the web, but not FTP

But #11797 says:

None of Amazon/Ceph s3 #11652, Swift #8633, ftp #5655, ftps/proftpd #9630, smb on FAT correctly propagates mtime changes up the directory tree, so our hasUpdated() fails and we have yet to implement backend specific implementations that work.

It might also depend on the FTP server. Some might deliver proper mtimes (in a format that the FTP stream wrapper from PHP is able to read) which makes it possible to detect updates. Some others might not.

Known issue no some external storages - we need to address this in 8.2. nothing we can do in the livecycle of 8.1

[PVince81]

General ticket: sort out external storage update issues: #11797

[PVince81]

@DeepDiver1975 move to 9.0 ?

@DeepDiver1975 move to 9.0 ?

yes from my pov @cmonteroluque objections?

@DeepDiver1975 @PVince81 Yeah, part of the overall issue with external shares. Tough to accept but no choice at all.

[PVince81]

@DeepDiver1975 @icewind1991 what about the flysystem FTP implementation ? Didn't we want to replace the existing one with this new one ? Would be good to find out whether it fixes the mtime based change detection problem.

[PVince81]

Moving to 9.2

[PVince81]

Please try again with the "files_external_ftp" app which is based on flysystem.
