Logging won't show anything in this case.

Do you have some plain FTP server, with which you can try to test this behavior?

I use only SFTP. But I just opening another session with SCP and it failed with same error.
Also, today my first session failed too when i try to update and save a file on the remote server.

If i can generate DEBUG2 log, would it be helpful ?

Does it matter what protocol the first or the second session use?

Hi Martin,
Yes. As soon as i open a second tab I start seeing this issue. I usually have 4-5 tab/host to work with.

Do you get this problem everytime you try to open a second session from WinSCP? Does it matter what protocol is it?

Hello,

I have been using winscp for quite some error now, but not able to figure it out what is happening now.

I open a winscp connect to one host and then I open a new tab to connect to another host I get below error message
Network Error : Windows Error Code 10093 (and Format message returned 122) error

When I retry to connect to different site/host I get below error message.
gethostbyname: unknow error

Now my first session is also useless and I have to close the winscp and open a new one. I have done the uninstall and re-install etc . Didn't work.
