i just tried to use the SFTP Plugin to get some files from my Synology NAS (DS211j).
As i don't want to expose the SFTP port in public i tunnel a local port (port 9999) via Putty to the destination port at home (port 31337).
After configuring SFTP Plugin (started with v1.3) i can connect to my NAS using SFTP just fine and the directory listing seems to be quick.
However, when i try to transfer files either the files i download are 0 bytes, or if i try to upload a file, TC crashes completely.
I'm using TC 8.0 x64 and also updatd SFTP Plugin to v1.4 now. I Rechecked that i use the latest version of the cURL library that is linked from Ghisler.com's WFX Plugin list.
It is:
MinGW64 7.29.0 devel SSL SSH Günter Knauf 2.15 MB
I tried to make sure my NAS is not the problem. If i use WinSCP (also using the SSH tunnel via Putty) the transfer works just fine.
Is there any suggestion what i should try find out what causes the problem, or where to look for someting?
Or might the problem be that tunneling is the problem for TC?
Update before posting

I tried to not tunnel SFTP directly but using Putty as Socks Proxy (shouldn't be too much difference anyway) with almost the same result: file transfer is not working in any direction but TC seems to not crash directly.
Thanks for any help!
