Syncing client crashes with "Network Error:99"

same issue here. It is ok when drag & drop on a web browser.
FYI, my system : raspberry pi os 64 / bullseye / nextcloud 25.0.1 / client under Ventura

Many thanks

Same for me. Network error: 99 on macOS 12.6 clients (M1 and Intel).
At the moment, the clients are beachballing.

Pop!_OS 22.04 LTS
Nextcloud 25.0.1
Apache 2.4.52-1ubuntu4.1
PHP 8.1.2-1ubuntu2.8
mariadb Ver 15.1 Distrib 10.6.7-MariaDB
Installed on my box using Learn Linux TV’s procedure

Thanks for any suggestions!

Try uploading Ghidra (unpacked ofcourse), but the weird part is that that when uploading the same via the webui another error occurs: “An exception occurred while executing a query: SQLSTATE[40001]: Serialization failure: 1213 Deadlock found when trying to get lock; try restarting transaction”

Same issue with a debian 11 and Apache 2 php 7.4
Thanx for suggestions !

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

It looks similar to my problem;

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…

  • Reinstalled using Postgres instead of MariaDB
  • .well-known redirects all working correctly,
  • Redis set up
  • No warnings on Admin Overview

The same client works on the old Ubuntu 18.04 server running NC 20.0.14 without any of these issues.

Same problem like @targren. Please!

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

<VirtualHost *:443>
  ServerName cloud.example.org
  ServerAdmin webmaster@example.org

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:

  • On the client, disable any upload speed limits
  • On the server, edit 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.

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.
