The problem happens rarely. I cannot reproduce it.

In WinSCP, I reconnected my session, then tried to open a log file that I had previously viewed a few days ago. I got the error message below, so I refreshed the directory and tried opening the file again.
See attached screenshot.
I tried opening some of the other files and got the same error.
By the way, I have some windows updates that are staged waiting for me to reboot. I will try that, but will lose this internet session when I do it. If I can get back to this posting I will let you know the outcome.

The problem happens rarely. I cannot reproduce it.

- When i let the tunnel connection idle for three days and let it disconnect, and then create a new tab on WinSCP, this error pops up preventing me to create the new tab. Already open tabs can reconnect as usual. Happens rarely.

I made some file transfer, then left connection open but idle in background.
Connection was via a SSH port-forward using SOCKS proxy.
Later the SOCKS proxy closed unexpectedly, so the connection was lost.
When I return to computer 6-7 hours later the error message was popup on the screen.

Hello. This issue happened when I traveled from one place to another several hundred km away. I used it
on a local Wi-Fi network to connect to a phone. After that my notebook was not shut down and I found out when I plugged in the power supply while arriving. Then the software popped this error message.

Hello, reporting this error as requested from the app when it occurred - I had been on leave from work last week and had left WinSCP open and connected to one of our client sites, so unsure if this was simply some sort of timeout issue or not, and is the first time I've ever seen it, but simply reporting as the error message requested so. Thanks.

The problem happens rarely. I cannot reproduce it.

@sunitshah.9995: Thanks for your report.
