SFTP Upload stops by 102400 Bytes

Hi guys,

the title already describes my problem completely.
When I upload a “large” file, the upload stops/hang (await) exactly at 102400 bytes; without error message.
No complicated setup. I simply load a file from disk and want to upload it via SFTP.

Can someone help me with this, please?

Update: n8n has no problems with FTP upload. The SFTP-Server is also well configurated; upload with FileZilla and SFTP works.
