Hanging forever issue

[zipelkopf]

Do you read the FAQ?

• [x] Yes.
• [x] I am going to read now.

Describe the bug Sometime the extension stops working with the little SFTP icon spinning in the footer-bar of VSC. When checking the output log the SFTP tranfer looks like stuck and the file never gets uploaded. Nothing times out and the only way I found to make it working again is to restart VSC. This happens very irregurarly, from once in a hour to a few times in a row. I checked my internet connection and my remote server but in all occasions they were always up. Please see screenshot and debug log attached.

FYI, I have tried on both a Windows and Mac computer, same result.

** Debug log, at the beginning you can note the SFTP works, then it hangs even when trying to save/uplaod again.

Could you try my version and tell me if it fix your problem ? You can find it here.

[zipelkopf]

Thanks @Natizyskunk, I have just switched to your version, so far so good but let me try it for a few days and I keep you posted.

All the best!

[Natizyskunk]

@zipelkopf, No problem 🙂

Thx !

[jeffglynn]

I still have this problem with the SFTP hanging on the @Natizyskunk version

[juliemoffat]

Same issue with @Natizyskunk version. Version: 1.69.1 of VSC and fresh download of SFTP as of 9/1/22. Freezes with spinning arrow on the remote folder I'm trying to toggle open. Only way to keep working is to restart.

[wickedpixel]

Any fix to this?

[zipelkopf]

Hi all, my original problem is no longer presenting itself so frequently with the latest version ...still getting it but not terribly.

By the way, I recently changed FTP server and a similar problem occurred. It was to do with the fact that my FTP server is behind a NAT: the whole secure connection worked but no data was exchanged via the passive ports, causing the forever hanging effect...

Because of the NAT situation, I had to set on my FTP server (i.e. Pure-FTP) the setting ForcePassiveIP to the server public IP address. Then the hanging in VSC stopped and all works fine.

Cheers

Indeed, this is the solution to the problem. Thank you very much for your support.

[jeffglynn]

That doesn't help if you don't have control of the server
