I am also having similar issues. It only seems to be affecting one client across 4 servers so far. It seems to exploit a memory leek on windows as it keeps eating ram each time it it attempts till it makes the client machine unusable.
I am also using debian , apache 2 and php7.4

My windows apps loop many files (about 4000) with error 99, the memory increase to the max, the windows begin to be unstable and many apps crash.
It’s totally unusable
Thx !
Having the same problem, too, on my local network (1 Gib). It’s driving me nuts. Hundreds of “Network Error: 99” messages choking my sync with the client until it stops responding completely and I have to kill it with the task manager, and nothing showing up in the server logs to give me the slightest clue what the problem is.
Client: Windows 10, Nextcloud client 3.6.2
Server: Ubuntu 22.04, Base install Nextcloud Hub 3(25.0.1) of Apache
I’ve tried all the fixes I’ve seen mentioned here, github, reddit…
The same client works on the old Ubuntu 18.04 server running NC 20.0.14 without any of these issues.
Same, Following.
Linuxserver:latest - unRaid - Using MariaDB and Redis.
Latest Mac client - Ventura
Up the folder to the Cloud, and sync from cloud to a new folder, work for me! Its somthing.
I’ll join in.
Files created on the client will not be synced to the server, client log show “Network Error 99”
Everything freshly setup on Friday in a new Ubuntu 22.04 LXD container, mostly following
Everything else seems to be working fine.
Apache proxy config on the gateway container is

I have been hitting “Network Error 99” and the Desktop client freezing up since upgrading to NextCloud 25. I finally found a fix discussed in GitHub issue 5094, in summary this is what fixed it for me:
config.php to add the line 'bulkupload.enabled' => false,
From the discussions on GitHub, it sounds like the upload speed limit and bulk upload features are buggy in the latest server/desktop releases.
Hi @joshuaprince , thx for your fix, it’s work for me, after edit the config.php and restart, the client have sync without error !
Worked for me also. Just added the line into config.php. Thank’s Joshua…
Works fine here to ! i had no limits enabled at all but the function some how is broken and cause lots of errors 
thanks for your solution !
Hello,
I have the problem of these errors 99 on a fresh install.
This solved it for me perfectly. Had to wait forever for Nextcloud to revalidate the sync, but then it suddenly finished and got the big green checkmark.
great ! Works for me too !
Why is this still not fixed? I also had this problem.
Works for me as well. This problem still exists.
I have the same problem, I cannot find a solution and PLUS since I’ve installed Nextcloud I have a lot of problems with windows app icons and preview of a lot of files in other windows apps.
I already wrote to Nextcloud with their website form but no-one still answered me… I’m so upset!
This DOES work, HOWEVER, it make the transfer of small files very slow. Seems like there is probably a better solution.
this was really good and everything was solved.
thanks!
