Users have been uploading for months and now can't
Posted: 2018-07-23 19:42
Hi,
I have had users logging in and uploading files to our sftp for a few months now with no problems. This is a daily occurence. They recently brought to my attention that they are getting errors and can no longer upload files. I have changed nothing on the server since I set it up a few months ago. When I logged in from home, outside of the office network it worked fine for me. I also just tried it using my hot spot from my cell phone and it worked as expected.
Here is what the log shows:
