Upgraded with Latest SFTP Download; Now Won't Connect

Hi, try to raise the timeout to the connection.

Hi, try to raise the timeout to the connection.

I changed the timeout from 20 to 9999. At 20 seconds after FTP>RECONNECT, I got this message:

"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."


NOTE: Also, Keep Alive is enabled/checked with an Interval of 951 s (seconds?)

What's next to try?

Thanx again, Herb

I have encountered the same problem as Herb (and have followed these and other posts in search of a solution): after upgrading to v1.5.988.36, the following [edited for security] is logged whenever I try to get on to any site:

SmartFTP v1.5.988.36

I do not have a firewall. I accessed one of the sites within the last 48 hours using a previous version of SmartFTP and had no difficulty. I am quite sure the FTP server settings are correct, though I did try using the IP address instead of the host name as well (no luck there either). Settings>Connection>Keep Alive is set to 9999 seconds, and General>Connection>Connection Timeout is set to 120 s. I get the above connection failure notification after 20 seconds each time.

Any help would be much appreciated. Thanks.

Try Active Mode (PORT) instead of Passive Mode (PASV).

Theseus -- In my case, I believe I was using an old/outdated servername with Comcast. You may want to check with your ISP to ensure you are using the correct name. Comcast changed theirs, without notifying its users.

Thanks, Herb -- I had seen your post about that and looked into that problem, but confirmed that the servername had not changed.

Many thanks, mb -- switching from passive to active mode did the trick. All systems are go.

I'm already in Active mode and having the same problem. Any help?

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.

Same problem here.
