Sorry, I do not have any suggestion for you.

Yes. Any other ideas/suggestions? It's also not working on a new Server 2012R2 OS either.

Thanks for your help so far. At the moment I'm not sure what to try next.

Yes, it looks like the same problem.

Hi Martin,

I've tried to connect using FileZilla on both servers and neither will connect this time. I get this error

Response: 234 Proceed with negotiation.
Status: Initializing TLS...
Error: GnuTLS error -12: A TLS fatal alert has been received.
Error: Could not connect to server

I think this is to do with incorrect Ciphers when I do an Internet search. Not sure if this is a similar issue with WinSCP?

Thanks

Hi Martin,

I have installed version 5.7.7 on the other machine and it still connects fine. I'm wondering what could be stopping it on the non working server. I'm also positive it's not firewall related.

Thanks

You are using WinSCP 5.1.8 on the other machine. Maybe the server uses some deprecated cipher or version of SSL, no longer allowed in the latest version of WinSCP.

Can you try using 5.7.7 on the other machine?

Hello,

I'm using version 5.7.7 (Build 6257) of WINSCP to connect to an FTP site using FTPS protocol. It is running on the Windows 2008 SP2 OS.
I am using the script interface specifying the ftp site, certificate and also the -explicitssl setting.

I am getting this error below

> 2016-08-23 11:30:59.578 AUTH SSL
< 2016-08-23 11:30:59.582 234 Proceed with negotiation.
. 2016-08-23 11:30:59.838 SSL3 alert read: fatal: bad record mac
. 2016-08-23 11:30:59.838 TLS connect: failed in SSLv3 read finished A
. 2016-08-23 11:30:59.838 Can't establish TLS connection
. 2016-08-23 11:30:59.838 Disconnected from server
. 2016-08-23 11:30:59.838 Connection failed.

I've tried this exact script and WINSCP version on a server running Windows Server 2008R2 which works! I've also tried to download the latest version of WINSCP to see if that fixes it but I'm getting the same error message.

Please help as I'm stuck now.

Thanks

Adam
