Synchronization Stops due to 'OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 104'

[QihanLiu]

Bug Report Details

Describe the bug
I am syncing all the files to my new computer. Synchronization stops when only a few files are downloaded. I have to use the same command to force sync multiple times (20 times maybe).
There is no bug appears. It acts simply like sync finished.
Usually, it stops after getting stuck in downloading a file. At least it acts like stuck, but it can download the file after rerun the same command.

Application and Operating System Details:
Ubuntu, 18.04.4 LTS.
Exchange OneDrive Account.

Please update your first post above with all the required information when raising an issue as per https://github.com/abraunegg/onedrive#reporting-issues

@QihanLiu
Please can you respond and provide the required details.

@QihanLiu
Thanks for the debug log.

As no error is being generated or throw & there is no evidence in the debug log that there is an issue, a further HTTPS debug log needs to be generated to see what is occurring at the transport level.

Please generate a HTTPS debug log as per https://github.com/abraunegg/onedrive/wiki/Generate-https-debug-log-for-support that captures the sync 'stopping' as per your experience.

Sent.
The zip file contains 2 log files.

I also found out that I've synced 31 times to download all the files.
Because each unsuccessful sync was caused by failure in downloading a file, that failure edits the modified date of that file.
So, at the end of synchronization, the program would identify those files as new files and upload them.
I have to manually restore those files to the previous version.

Hope that helps.

Thanks for the debug logs.

The reason for the failure is the following:

OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 104

These SYSCALL errors are almost invariably due to server or network issues.

Refer: curl/curl#4409 (comment)

This is not a bug with this client. Most likely:

• You have some sort of flaky Internet connection somewhere between you and the OneDrive service
• You have some sort of 'broken' HTTPS transparent inspection service inspecting your traffic

Your Curl version is also 7.58.0 where as the latest is 7.68.0 (Refer: https://github.com/curl/curl/releases) - suggest you also update your Curl version to something a little more modern to see if that also assists with the issue.

[QihanLiu]

I am not sure that is the reason, but after I installed curl (version 7.68) it stop working.
For all the command (sync, monitor logout etc), showing:
"Cannot connect to Microsoft OneDrive Service
Reason: Unsupported protocol on handle 55E5E44B0190"

Also, in apt-get, curl version is still 7.58.0-2ubuntu3.8, not 7.68.
But if I run "curl --version", it shows curl 7.65.3 (x86_64-conda_cos6-linux-gnu).
I searched for a quite a while. nothing works.

@QihanLiu
Unfortunately you need to take this up with Ubuntu support / Curl support.

Your issue is related to the reasons provided above.

If the upgraded Curl version does not work for you, please open an issue tracker with Curl.

Please review best course of actions for yourself, and how to debug your SSL/TLS problem.

Closing issue, not a bug with this client.
