TLS connect: error in SSLv2/v3 read server hello A

Getting the error in the subject line when trying to connect to a server. They specified to use explicit FTP over TLS. I can get connected in IpSwitch, but not WinSCP. I attached a log showing the error.


Thanks

What version of WinSCP are you using?
Show us IpSwitch log file too.

Thanks for the response. I am using 5.9, but I upgraded to the latest version and got the same error. Here is the IpSwitch log. I connected in IpSwitch and navigated to one of the folders, so the log below is showing that.

While you connect to implicit TLS port 990 with Ipswitch too, the protocol used is explicit TLS. It seem like a misconfigured FTP server.

Try forcing WinSCP using explicit TLS, while still using implicit TLS port 990.
