Cannot Connect

I recently updated my license for SmartFTP and since I have not been able to connect. I also have changed ISP's and that may be an issue. I have tried to troubleshoot by pinging the ISP, router, and host with success. Appears that all IP's are valid. I also increased the timeout of FTP. Here are the messages I am receiving:

Hello ..

Try to use the "Normal FTP" protocol instead of "FTP over SSL". To change it go to the General dialog in the favorite settings.



That appears to work. However, is there any consequence to not using SSL? I have always used it in the past with no issues. Not sure why I cannot use it now.


If you use FTPS (FTP over SSL/TLS) the protocol information (e.g. username/password) are transferred through a secure channel. If you use FTP the data is sent in clear text.
The problem in your case is that when using a secure channel (FTPS) your router is not able to read the commands in your session and therefore is not able to automatically setup the correct entries (for port forwarding etc) in its NAT table. You can workaround the problem by changing the data transfer settings in SmartFTP but this might not work either. Using the FTP protocol is the "easier" but less secure solution.
