Uploads stop after around 15% (wodSFTP / wodSFTP.NET / wodSFTPdll)

We are uploading to a sftp server. The connection succeeds, and we start to upload the file. After a very consistent amount of upload the connection is terminated with an error "An existing connection was forcibly closed by the remote host". Any ideas as to avenues to pursue.

We are also getting an error from two other customers indicating that there is a "corrupted mac on input". These sftps were working prior to the update.

We are currently using 3.7.2.

It appears this may be the root of all of the errors. The original customer looked in their logs, and sees that same error. I am assuming this is the root cause.

Any ideas?

Hi.

Can you check if HMAC algorith used in the connection is hmac-sha2-256-etm@openssh.com or hmac-sha2-512-etm@openssh.com? You can find that info in CryptoInformation event.

If it is, please request update, we published possible fix yesterday, so hopefully issue is gone.
