Been using WinSCP very happily for many years, then two days ago - BOOM - cannot connect to any servers!...

Did you try any other FTP client?

Yes, it works with FileZilla - but only on the second attempt every time. I get a timeout on the first attempted connection, but it connects second time round. Very odd!

I am lost without WinSCP. I have tried changing all the advanced options, adding exception to firewall, different PCs and even the router. Nothing seems to work.

If I uninstall and reinstall WinSCP it will randomly connect once, but never again!

I have also checked for and removed any spyware / viruses.

I am baffled.

My six year love affair with WinSCP could be at an end. FileZilla is fat and ugly in comparison, but I cannot work without any ftp at all.

:cry:

Can you please attach a complete log file from FileZilla, both for the first failed and the second successful attempt?

Thanks for your report.

Can you send me an email, so I can send you back a development version of WinSCP to track the problem? Please include link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.
