Your top, ask everybody to help, the whole days also didn't understand it,,,

CodePudding user response:

The server certificate is necessary, the client certificate is not required, you can see the FTP client setup certificate, otherwise the SSL can not be normal operation, the SSL is inherently requires server must have a certificate,

CodePudding user response:

Server is set up customer, should be have a certificate, certificate information with FileZilla connection when prompted. I thought the client side also need the certificate at the beginning, ask the customer, not to provide my card doesn't know how to do

CodePudding user response:
