Perhaps try this:

Configuration > Options... > FTP > [x] Create a log file.
This also logs all plugins like SFTP
Post it here.

Conceal personal details, but keep as much of the punctuation and special characters as possible.

Please check whether the file sftpplug.ini is corrupted. It should be in the same directory as the wincmd.ini.

Reason: There seems to be a bug in the 64-bit optimizer of the C compiler which corrupts writing to ini files. I have disabled optimization now, but it was enabled in earlier versions of the plugin.

I get the error trying to connect to the server: "Timeout waiting for response from SFTP subsystem". Connection to the same server from Bitvise SSH client works without any issues.
Would be grateful for any hints!

Here's my tcftp.log:

Thanks a lot!!!

P.S. for those with the same problem: the option is called "Use SCP for everything (no SFTP)"

ouch... With this option enabled I can list the directory but not the file content: get "SCP download error: SCP_PROTOCOL (28)" or "SCP upload error: SCP_PROTOCOL (28)"

[ghisler(Author)]

When you choose "Use SCP for everything", TC uses the normal "ls" command to get directory listings, and SCP for uploads and downloads. This way it doesn't need to use the SFTP subsystem at all. Apparently your server does support the "ls" command, but does not support the SCP commands for file transfers.

How long does the login take with Bitvise SSH client? The SFTP plugin successfully logs in, but the call to libssh2_sftp_init seems to time out.

[ethidium]

with Bitvise client, login takes about 2 seconds, according to its timestamps

[ghisler(Author)]

A 2 second delay should not cause any timeout. Do you get any log frrom bitwise?

Maybe you could ask the server maintainer to allow SCP transfers? They are normally enabled with SSH, and they are much faster then SFTP.

[ethidium]

Unfortunately I don't have direct communication with the server maintainer (plus it's a corporate server and they are unlikely to change anything).
I'm attaching a screenshot with Bitvise log, don't know if it's helpful...

Maybe the following is confusing the libssh2 I use:
SFTP channel: pre-SFTP data received

Are you running a logon shell script in your SSH account? If you don't be careful, it will be run also in non-interactive sessions and will cause all kinds of troubles.

Thanks a lot Christian!!! Indeed I had a .bashrc file there - after I renamed it, everything came back to normal!

[ghisler(Author)]

You can keep your .bashrc, you just need to check whether you are doing an interactive login or not.

Here are some methods to check this:

SFTP plugin 2.80 final is available now! See the first post for details. Download links:
SFTP Plugin 2.80 (Windows Vista, 7 or newer)
Sources
Windows XP version

It now prefers curve ED25519 host key if available, which may lead to warning that the fingerprint of the server has changed. This is normal because each host key has its own fingerprint. So when a different host key is used (e.g. RSA -> ED25519), the fingerprint will be different too.
