Network error: Software caused connection abort during key exchange

Hi,
First of all your product has made work life so much easier. Greatly appreciate your hard work developing WinSCP.

Question is that we are having intermittent errors below during what appears to be the key exchange. I say it is network related but the network team is saying otherwise.

Would like to hear your opinion and if there is something we can do to prevent these intermittent errors?

Second question, how do I disable WinSCP caching using Winscp.dll 6.3.2 with VB.NET?

Thanks for your support! It is greatly appreciated.

Re: Network error: Software caused connection abort during key exchange

Sorry, hard to tell. It can be a network issue. But it can also be some server-side problem or incompatibility between WinSCP and your not-mainstream SFTP/SSH server.

I'm not sure what "caching" you mean.
