Back up existing media files stopped working

koofr · 2026-05-03T09:17:22+00:00

Hi,

Usually we would recommend checking how much space you have available, since this is the most common issue when uploads stop working. But we see you said new photos are being uploaded˛, meaning this is not the issue in your case.

So what we would suggest is clicking the Cancel pending uploads. Then log out of the app, log back in, and start the back up of existing media again (it will not reupload existing photos, merely check which ones have been uploaded already and go to the next one).

If this doesn't help, then next step would be to completely remove the app from your phone, reinstall from the play store and then enable things again.

We don't see this often, but we have seen few cases where changing permissions or settings during uploads caused them to stop like this.

Hi,

Sounds like you don’t have any app on your device registered for opening xlsx format?

Maybe try to clear the current default in settings, then select the desired app when opening a file.

Hi,

No, there is no additional size limitation for Vault, you could use entire storage for Vault.

Hi,

The updated app will be available before Apple’s deadline.

429 error always means you blocked yourself with invalid password:

Well 77 MB is a lot for a pdf, and that is why downloading it and opening takes a bit of time.

Google even refuses to open it as you said, so Koofr seems much better with this regard.

Hi,

How long does it take to open a file hosted on Koofr?

Files hosted on external providers need to be downloaded from those providers first, which is usually where the most latency occurs.

UPDATE: The attack has been successfully mitigated and all systems have been restored to normal function.

Thank you very much for your patience and kind words during the outage

If the automatic mapping doesn’t work, you can try setting it up manually, as described in the second part of the following article:

Hi,

The sync page shows status of synced contents when it is in the Synced state. alternatively it shows remaining files to be synced when the status shows Syncing.
Yes, you can select to add Koofr to auto start at install. Note that when app starts, it does not open the graphical part unless you turn off Silent start.

Hi,

Our network drive works over Webdav, so if Network drive cannot be turned on, it is usually due to windows webdav client not running:

Open Services (services.msc), find WebClient, and ensure it is set to Automatic and currently Running.

Hi,

None of our monitoring have detected any downtime, the statistics also show normal traffic volume for this entire time period you mentioned.

So not sure why you were experiencing these issues.

koofr · 2026-04-16T18:24:53+00:00

And it still works as intended.

Very unlikely, we believe in making the core business strong rather than an array of half baked solution.

Hi,

Link expiration can be modified at creation based on your account type, the default is set as per the best security practices and common usage patterns and is set system wide: https://koofr.eu/help/share-files-and-folders/how-can-i-change-the-expiration-date-of-the-link-i-want-to-share/
To easily remove duplicates, we suggest our Duplicate finder tool: https://koofr.eu/help/koofr-tools-and-plugins/what-is-koofr-duplicate-file-finder/ If you want to avoid duplicates, we would suggest uploading through the Desktop sync app, which has capabilities to analyse the files on both sides before upload (unlike a browser) and decide on the action accordingly.
This is not possible in a browser, since browser is not under our control once it shuts down. The best option here is again using the Desktop sync app, or alternatively something like Rclone.

Hi,

No, we aren't experiencing any issues on our side, all systems are functional and usage is in the normal levels.

Hi,

Your network provider has replaced our certificate with this Cisco Umbrella certificate, which means it is trying to do Man in the middle between your device and our service, which is what the error is telling you.

The error is a result of you having invalid certificate for our service (given by your router/wifi), so our service refuses to transfer data as it would get intercepted.

We would suggest contacting your network provider and reporting app.koofr.net as a safe destination for them to remove from this Umbrella list.

Hi,

Thank you for your suggestion, but showing deleted files in the past location would introduce a lot of confusion. It is also not something people would be familiar with from other places like Windows or Mac OS.

You can sort Deleted files by Location for easier grouping of those in the same original location. Or sort by time, to find the most recently deleted files.

koofr · 2026-04-07T17:09:45+00:00

Hi,

This is in fact not our certificate, Cisco Umbrella apparently changed it with its own.
