Describe the bug

The following scenario from the tst_syncing suite is failing in CI on step And the user waits for folder "myFolder" to be synced but is passing locally.

    Scenario Outline: Syncing a folder to the server
        Given user "Alice" has set up a client with default settings
        When user "Alice" creates a folder <foldername> inside the sync folder
        And the user waits for folder <foldername> to be synced
        Then as "Alice" folder <foldername> should exist on the server
        Examples:
            | foldername                                                               |
            | "myFolder"                                                               |
            | "really long folder name with some spaces and special char such as $%ñ&" |
            | "folder with space at end "                                              |

Expected behavior

Expected folder '/tmp/client-bdd/Alice/myFolder' to be synced.

The error message in GUI log is something like this

failed in different scenarios due to the same reason

    Scenario: Syncing folders each having 500 files
        Given user "Alice" has set up a client with default settings
        And the user has created a folder "folder1" with "500" files each of size "1048576" bytes in temp folder
        And the user has created a folder "folder2" with "500" files each of size "1048576" bytes in temp folder
        When user "Alice" moves folder "folder1" from the temp folder into the sync folder
        And user "Alice" moves folder "folder2" from the temp folder into the sync folder
        And the user waits for folder "folder1" to be synced
        And the user waits for folder "folder2" to be synced
        Then as "Alice" folder "folder1" should exist on the server
        And as user "Alice" folder "folder1" should contain "500" items on the server
        And as "Alice" folder "folder2" should exist on the server
        And as user "Alice" folder "folder2" should contain "500" items on the server

Though the scenario passes in CI, it fails locally with the error Connect could not be established, try again later.

And on debugging we found that the failure was because the connection with the socket could not be established. If we add a wait of around 2 seconds, the test passes locally too. But as the test is not failing recently on CI, for now, we can stop investigating this issue.

[sushmita56]

The file syncing problem is found to be a reason behind the failure of this scenario.
Currently, the sync issue is under investigation so this issue is unassigned for now.

I think this issue is related to: #9952 (comment)

[sushmita56]

This issue seems to be similar to the issue #9952 as the screenshot generated by this issue's debugging PR is exactly the same as the screenshot reported in the issue #9952. Previously the debugging PR was passing on CI but on the later run, it failed on step And the user waits for folder 'folder with space at end ' to be synced

Screenshot generated:

So I think this issue can now be closed in reference to #9952, however, the problem of socket connection is still there while running the scenario locally.
