Auto-Upload - conflict for not-existing files on server side (and upload does not work) #10423

habakuk007 · 2022-06-21T13:34:14Z

The Auto-Upload worked fine - then I upgraded to Nextcloud Server 23 (from 22 or 21) and also upgraded the Android app.

Since then the app tells me, that every new file is already on the server and does not upload any file.

End of original .htaccess:

ErrorDocument 403 //
ErrorDocument 404 //

I tried to adjust the .htaccess file and removed the redirection to the 404 document (I did not touch this file before!).

ErrorDocument 403 //
# ErrorDocument 404 //

Now the upload seams to work again.

Expected behaviour

It should upload my images like it did before - without manual hacks

Actual behaviour

It does not upload any file or picture (without manual hack)

Can you reproduce this problem on https://try.nextcloud.com?

Did not try yet.

Seems that I am also affected: #7905 (comment) ..

Knusper · 2022-06-26T17:10:01Z

I can confirm that this workaround works.

szaimen · 2022-06-27T11:30:20Z

Do you really have this double slash here? Does it work also if you change it to ErrorDocument 404 /

Knusper · 2022-06-27T13:33:32Z

I just checked the .httacces that ships with nextcloud Server
https://github.com/nextcloud/server/blob/master/.htaccess

It does not contain these lines. Does it append stuff from a previous incarnation of this file during installation? If so, this must have been the default settings my hoster put there?

(Edit: Reading the changelogs from my hoster, I even find a mention that the Error Document feature is now available to users - so maybe they made a mistake in the default settings?)

szaimen · 2022-06-27T17:27:16Z

Yeah, that may be possible...

Hi @Knusper,

I have not added those lines and I'm sure my hoster hasn't not either.

But I found this: https://github.com/nextcloud/server/blob/7acb438e428e5b0b3a79c2b7ce5a4283b0e805eb/lib/private/Setup.php#L490

It looks like Setup.php adds these lines to the .htaccess.

Regards!
Stefan

szaimen · 2022-06-27T21:59:42Z

Yeah but does it work with a single slash for you?

habakuk007 · 2022-06-29T10:22:02Z

Hi @szaimen, there is no difference between ErrorDocument 404 // and ErrorDocument 404 /

habakuk007 · 2022-06-29T13:02:40Z

I also noticed that, if I make an update of the Nextcloud Server the ErrorDocument 404 // line is added again to my .htaccess file.

Knusper · 2022-07-15T14:04:07Z

Yes, I can confirm. But now I don't get file conflict warnings anymore, the upload of new files just fails with connection error.

rndph · 2022-07-24T13:13:30Z

I can confirm having the same problem.

Tested by installing a the newest stable server version 24.0.3 via the web installer, installing to the "." directory, using the default SQLite DB and not installing the recommended apps.
The .htaccess file got the line ErrorDocument 404 // added.

When trying to upload a file (not even using the auto-upload), this is shown in the webserver access logs:

[24/Jul/2022:15:03:12 +0200] "HEAD /remote.php/dav/files/admin//IMG_20220123_113042.jpg HTTP/1.1" 302 0 "-" "Mozilla/5.0 (Android) Nextcloud-android/3.20.3"
[24/Jul/2022:15:03:13 +0200] "HEAD /index.php/apps/dashboard/ HTTP/1.1" 200 0 "-" "Mozilla/5.0 (Android) Nextcloud-android/3.20.3"

When removing that ErrorDocument line as OP mentioned, it works:

[24/Jul/2022:15:08:53 +0200] "HEAD /remote.php/dav/files/admin//IMG_20220123_113042.jpg HTTP/1.1" 404 0 "-" "Mozilla/5.0 (Android) Nextcloud-android/3.20.3"
[24/Jul/2022:15:08:54 +0200] "PUT /remote.php/dav/files/admin//IMG_20220123_113042.jpg HTTP/1.1" 201 0 "-" "Mozilla/5.0 (Android) Nextcloud-android/3.20.3"
[24/Jul/2022:15:08:54 +0200] "PROPFIND /remote.php/dav/files/admin//IMG_20220123_113042.jpg HTTP/1.1" 207 1173 "-" "Mozilla/5.0 (Android) Nextcloud-android/3.20.3"
[24/Jul/2022:15:08:55 +0200] "GET /index.php/apps/files/api/v1/thumbnail/256/256/IMG_20220123_113042.jpg HTTP/1.1" 200 27404 "-" "Mozilla/5.0 (Android) Nextcloud-android/3.20.3"

I tried it with an account on https://try.nextcloud.com/ a well. Interestingly it did work there.
They are using version 24.0.0 though, but I have also tried specifically with that version and it failed for me. But since that line in .htaccess might not always be added, this is not a good comparison without knowing what exactly they have in that file.

szaimen · 2022-07-24T13:26:07Z

cc @kesselb what do you think about removing the errordocument part in the updatehtaccess function?

kesselb · 2022-07-24T15:26:51Z

Looks related to nextcloud/server#33048

Sorry I don't know why we write ErrorDocument to .htaccess and if we still need it 🤷‍♂️

Knusper · 2022-08-13T00:26:28Z

Ah, thanks for pointing this out. My hoster configure the server as described there, and that's why I get this nasty error. Currently the only solution for me is manually editing the .htaccess file after each update.

RhizomaticNomad · 2022-08-29T13:02:53Z

I can confirm this error and couldn't share i.e. photos from an Android client as in this bug report #10628. "Solved" via editing the .htaccess file.

d-sko · 2022-09-16T21:05:08Z

Thank you! I couldn't upload files from my phones for months, with your fix it is working again, thanks!

TeaDrinkingProgrammer · 2023-03-06T10:49:35Z

Anything we can do to fix this except edit the HTaccess file? I have a managed Nextcloud instance, so I cannot edit the HTaccess file.

szaimen · 2023-03-06T10:50:19Z

I think this should be solved automatically with nc26...

TeaDrinkingProgrammer · 2023-03-06T10:51:12Z

Well, I have been trying to auto-upload my pictures to an empty InstantUpload folder and I get tons of conflicts and failed uploads, despite having tried 3 times.

szaimen · 2023-03-06T10:54:48Z

Well, I don't think you are running NC26 yet...

TeaDrinkingProgrammer · 2023-03-06T11:15:19Z

My NC version is indeed 25, sorry for that.

pokulo · 2023-11-06T19:16:25Z

Looks related to nextcloud/server#33048

Sorry I don't know why we write ErrorDocument to .htaccess and if we still need it 🤷‍♂️

Thanks @kesselb : It looks like ProxyErrorOverride On could be indeed the cause of this problem for me.

joshtrichards · 2023-12-07T14:19:41Z

This was a Server matter: nextcloud/server#33048 and has been addressed in all supported version of NC Server at this point.
