I can confirm this bug also on NC 23.0.0

[ghost]

I moved back to Desktop client 3.6 and no more issues.

[fightforlife]

Same issue on nc23 and windows client 3.4.0

[mgallien]

can somebody test if this PR is fixing this bug https://github.com/nextcloud/server/pull/30999 ?

[szaimen]

Hi, please update to 24.0.8 or better 25.0.2 and report back if it fixes the issue. Thank you!

Hi, please update to 24.0.8 or better 25.0.2 and report back if it fixes the issue. Thank you!

Hi. On 25.0.2 + client 3.6.4 (Windows) the same problem.

Windows Desktop Client GUI becomes really slow and says "network error 99" for a lot of files.

I found this in my postgreSQL log.

Faced the issue as well on Nextcloud 25.0.2 with Windows Desktop Client 3.4.1, reverted back to 3.3.6 and files sync.

Now the log shows issue #34958 but seems to work anyway.

Hope this helps to narrow down the problem.

Try setting the Download and upload speed to the server as "Unlimited" in the Nextcloud client settings.

[MichaKersloot]

Hi, took some time to check, but those settings are already on 'Unlimited' . I've found the setting: 'bulkupload.enabled' => 'false', and this seems (no surprise) to solve this.

Still an issue NC 25.0.5

[labor4]

can we rule out, this doesn't fix the md5 problem? (transaction_isolation = READ-COMMITTED)

[MichaKersloot]

No clue. I'm using Nextcloud AIO and that seems to pull postgresql

[labor4]

No clue. I'm using Nextcloud AIO and that seems to pull postgresql

the postgresql equivalent would be default_transaction_isolation = 'read committed'

in postgresql.conf

[szaimen]

The default is read comitted in postgresql apparently: https://postgresqlco.nf/doc/en/param/default_transaction_isolation/

[c-schulz-rd13]

Still an issue here as well!! NC 25.0.05 MariaDB with (transaction_isolation = READ-COMMITTED) (setting verified via 'mysqladmin variables') On Mac, Docker Desktop, NC docker-compose

I also see problems related to this issue.

@AndyXheli I agree the issue still persist with version NC 26.0.2 and NC 26.0.3. I'm using desktop client version 3.9 and I have configured transaction_isolation = READ-COMMITTED` and 'bulkupload.enabled' => 'false' . And I still get this error.

[Sieboldianus]

The first time I saw these errors was today, when adding Zotero storage folder to nextcloud. The folder contained about 15000 files called .zotero-ft-cache and all of these would trigger the Computed md5 hash error in the server logs.

Still an issue on NC 27.0.1

[Cl00e9ment]

So there is a hash mismatch between what the client computes and what the server computes. This means that it could also be a client bug. Seeing that all reports show a Windows user agent, I suspect that this a Windows client bug.

Also, on my NC instance, if I remember correctly, before disabling bulk upload with bulkupload.enabled' => 'false', it was a Windows PC that failed to synchronize and was creating those errors in the server logs.

[ganglere]

I'm having the same issue on a fresh install of NC AIO 27.0.2.1. Setting 'bulkupload.enabled' => 'false', did not work, but downgrading the Windows client to 3.3.6 did.

[mgallien]

if there is still an issue when running latest server and desktop client releases, it cannot fixed without providing server and client logs fixes were https://github.com/nextcloud/desktop/pull/5871 and https://github.com/nextcloud/server/pull/39221 as you can see one should run the 3.9.1 client release and any of the latest server releases including the PR or a backport of it

First time found with NC 27.1.6, client version Win 3.11.0.

[patrikroy]

Since a few days, and after syncing a fair amount of files, I got the same error on a NC 28.0.2, client version 3.11.1. Not sure if it is related, but the client computer went to sleep during the sync, and never managed to recover from it - client froze even after reboot. Had to reinstall it to continue the sync.

Same here. Using the latest Nextcloud server version (28.0.3). However with a old Nextcloud desktop client version (in my case v3.4.2), so make sure to update also the desktop client! Latest version of the client is version 3.12.0 at the time of writing.

Try setting the Download and upload speed to the server as "Unlimited" in the Nextcloud client settings.

Can confirm I was having this issue with MacOS client 3.12.3 whilst using a VPN to the nextcloud server. To fix, I force quit the client, start it, paused the sync before it could start and freeze and then went into the network tab and set it to "No Limit". Sync immediately worked once resumed.

[melroy89]

This is not good, correct? This can cause various sync issues? I really hope somebody knows how to fix this.

[ItsMeRitch]

Did removing the limits not help with your issue?

[melroy89]

I didn't had any network limits set to begin with. ..

[frlan]

I still can see it here too. NC 29.0.3 and Client 3.11 on Debian with PHP 8.1

[NorbiPeti]

I got this issue with the client completely freezing each time it attempts to upload some files. Removing the upload limit seems to fix this in my case (thanks for that). I turned off the automatic upload limit in nextcloud.cfg (useUploadLimit=0 instead of -1). Pausing from the config also works to get the client running in any case.

Running Nexrtcloud Hub 8 (29.0.7), I updated while this issue was present (to this version) and that didn't solve the issue. Also updated the client (3.14.0).

[melroy89]

Also updated the client (3.14.0).

Also.. try to downgrade your client. I got another ticket open here regarding 3.14: https://github.com/nextcloud/desktop/issues/7171
