The problem happens rarely. I cannot reproduce it.

The error was displayed on-screen after WinSCP was open all night on a laptop, which I do often. During the night I had issues with my firewall and DNS resolution stopped working, but there would have been access to the internet if connecting via IP. This is likely to happen again until I figure out how to fix the config issue on the firewall, so I'll try and replicate the issue by leaving WinSCP running nightly and see if it crashes again.

I've been using WinSCP for a few years now and have not run in to this issue before. It's a great piece of software, thanks!

Yesterday I used WinSCP to connect to a server through the company's VPN. I had left the computer open all night and eventually the VPN connection shuts down. The next day WinSCP showed this error.

Recently, whenever I try to open a text file (of various extensions), I get this error. I usually double-click the file to open, but I get the same error if i try to right-click then open, or right-click then choose a different text reader than the default.
The first time I got this error, I already had a couple of files open, and trying to open a 3rd file gave me this error. When I closed an open file I was then able to open another file in its place. But now (new session) I can't open any files at all and get the same error.

I know how to reproduce the problem or the problem happens frequently enough. I wish to be contacted by the WinSCP team to help resolving the problem.

@ai.alateeqi: Thanks for your report.
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.

I was trying to submit my job, and I went to go see the file that I copied over to go to the cluster, and clicked on the file name, and this error message came up, preventing me from being able to see the file contents. It shows up periodically and disappears randomly. I first noticed it today, 7/20/22, at around 4pm.

The problem happens rarely. I cannot reproduce it.

I was just dragging a file from the local side to the remotes side. I tried several times and got the same error. I navigated to different directories on the remote side and the navigation worked. I tried closing the session and reopening it and that got a similar error. I closed WinSCP entirely, went back in and all was fine.

I know how to reproduce the problem or the problem happens frequently enough. I wish to be contacted by the WinSCP team to help resolving the problem.

@depiedo: Thanks for your report.
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.
