Thanks for your report. Let us know if it happens again and find out how to reproduce it.

I disconnected the session and then reconnected to continue the process.

I had selected 9 files to delete all at once, and only one of them had been deleted during the process which ended with the error (there were 8 remaining). Don't know if this is useful info, but I thought I'd add it anyway.

I was connected to an SFTP server, getting ready to delete some files from that server, when a phone call came in. I got the "disconnected, retry in n seconds" message, clicked the reconnect now button, and I _think_ that's when I got the error.

NOT positive about the exact steps, TBH, and as someone with 30+ years in software development, I'd say don't rely on that description as being 100% accurate.

Good luck!

The problem happens rarely. I cannot reproduce it.
