After uploading the recent update, I'm being prompted constantly about certificate issues with my server. After clicking that I do want to continue the upload it cranks for awhile, and then I get the following message:

FTP Error: Upload failed
I won't open a connection to 192.168.1.102 (only to 24.147.240.17)

Being stubborn, I keep clicking Try Again, and eventually it goes, but it's extremely frustrating (particularly when on a deadline).

Try to change the FTP connect mode to passive.

This problem is not closed yet. I and others have the same problem. See ticket #5179.

What is the solution? Hitting try again time and time again is not a solution I intend to use.

It looks like this issue is caused when changing the connection protocol to FTP-TLS instead of plain FTP.

It looks like this issue is caused when changing the connection protocol to FTP-TLS instead of plain FTP.

Some people are possibly hitting a interoperability issue with ProFTPD documented in #5087. Opening the data socket using passive connect mode (PASV) fails and the fallback to active mode (PORT) fails for most configurations. Hence the error message. Users should switch back to plain FTP connections. Choose FTP (File Transfer Protocol) in the bookmark protocol setting. Most users hit by this compatibility issue have been asked to secure the connection because support for TLS was detected upon negogiating the connection. Refer to switch to secure connection prompt.

If the above does not apply, make sure to check you have checked Use Passive FTP Mode (PASV) in the system preferences. Refer to FTP Connect Mode in the wiki.

As of a9e0ef6 the original error is reported and not the error from the fallback mode.

Duplicate for #5385. Will add proper fallback logic if the server denies PORT command.
