I am trying to send a file via code using FTPWebRequest (ftps,pasv). I am getting the following error:
Unable to read data from the transport connection. A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
I can connect to the host in question fine with FileZilla, but only after I accept the SSL certificate.
The code is working, as I am succesfully sending the file on another server which tells me it has to be a firewall issue with this particular machine. What do I need to tell the SA to do with the firewall settings that will (a) fix the problem and (b) not going to be a gaping hole in the server's security?
