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.

27

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.

28

great ! Works for me too !

30

Why is this still not fixed? I also had this problem.

31

Works for me as well. This problem still exists.

32

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.

34

this was really good and everything was solved.
thanks!
