HTTPS Client with FTP Login Error: javax.net.ssl.SSLException: 502 SSLv23/TLSv1 java
问题 I am pretty new to Java so the more you explain the more I learn, and less questions I will ask ;) I am trying to program a client to connect to ftp.availity.com but I cannot for the life of me get the client to login. I have tried changing the port numbers (443, 20, etc) but they all do not return a response in the console log and it only returns a timeout error. The only one I can get some action with is port 21. I know this is FTP and I think that may be where there error is coming from
