Bug description

The desktop client stops syncing with error "Connection Timeout".

Server is a fresh install via "Web installer" running on Ubuntu 22.

Logs:

nextcloud_timeout.zip

Screenshot

Steps to reproduce

• I have a data-set on the server of about 23GB +12000 Files.
• Login with the desktop client, select the folders to sync, enable "Virtual File Support" and all files get synced.
• Then select the root folder and enable "Always keep on this device". Now the sync starts, but stops occasionally on files with error "Connection Timeout".
• A Force Sync continous syncing but stops on other files.
• Limit Download Bandwith to "Limit automatically" (at least it seems so) runs and finishes without error.

Expected behavior

Sync finishes without error.

Same issue here. On our side it's happening when sync a pdf.
But in the log it's exactly the same issue

Exception No parameters in call to OC\DB\QueryBuilder\ExpressionBuilder\ExpressionBuilder::orX
Calling OCP\DB\QueryBuilder\IQueryBuilder::orX without parameters is deprecated and will throw soon.

@UH-Nerion
I am trying to investigate
do you have any UI visible when getting errors with the timeout of network connections ?

[mgallien]

to be more specific
I can reproduce when the activity list windows you get from the systray icon is open and not when it is closed

[GiambaFr]

Same for me, with or without the app's window open. Win 10 on a 100Mb/s connection.
On my other computer, WIN 11, WIFI 5Ghz, all seems OK.
Same versions.

[teclab-at]

I left the Settings window open, but the error happens even when it is closed.

@teclab-at @GiambaFr
I have a custom build with a possible work around for this bug
could you test it ?
https://cloud.nextcloud.com/s/cf4iBmPHxqdi7jZ
please keep in mind that this build just got tested for this particular issue not for general QA

[GiambaFr]

@mgallien
Ok, Just tested, 6GB transfered without any error.
Can't wait for a new mainline version.
Thanks

[elr3m]

Same behavior here (connection timeout and operation cancelled) on Windows 11.
I used @mgallien installer and it seem to have fixed it, I even unchecked and re-checked 22Gb of data and it all downloaded.

[UH-Nerion]

I installed your version, but same issue here.
Problem is not resolved.

[mgallien]

@UH-Nerion
what is the exact issue you get ?
could you share logs or screenshots ?

[UH-Nerion]

After 3-4 minutes it was working fine with your new release and the full sync was finished without any more errors.
Don't know why it was not working directly at the beginning.

[mgallien]

this is now solved with the release of 3.14.1

[GiambaFr]

Your test version was 3.14.50 isn't it?

[Gwindalmir]

I'd like to comment that while this did fix the syncing error on two of my systems, one of them (Framework 13) is showing more connection timeout errors after resuming from sleep (even tried toggling wifi after resume).
This is all while I can browse my nextcloud instance in Firefox just fine at the same time on the same system.
I had to restart the desktop client for it to resume. It's like it cached the error state and didn't actually retry.

I've attached the logs files from that session. I changed one of the last ones to remove the list of filenames it was syncing once it reconnected successfully.

EDIT: And I posted this without refreshing the page and noticed it's now closed. I'll test again with the updated release.
