Hello, any help would be gratefully appreciated.

I’m doing a ColdFusion to Lucee server and have had issues with my FTP connection.

The current code:

I get the following error message:
“ERROR”,“cfthread-87”,“06/25/2020”,“16:00:50”,“cfthread-87”,"Connection is not open;Connection is not open;lucee.runtime.exp.NativeException: Connection is not open

I’ve also tried:

new ftp().open( action=“open”, connection=“transferPDF”, server=“#theIPAddess#”, username=“#theUserName#”, password=“#thePassWord#”, port=“#thePort#”,transferMode=“binary” );

Get Error message:

I am able to connect if I go to the server and do an FTP.

Scratching head here…
Thanks in advance with any help.
David.

Code didn’t show up…

Example one.
cfftp connection=“transferPDF” username=“#theUserName#” password=“#thePassWord#” server=“#theIPAddess#” port=“#thePort#” action=“open” transferMode=“binary” stopOnError=“No”

cfscript
new ftp().open( action=“open”, connection=“transferPDF”, server=“#theIPAddess#”, username=“#theUserName#”, password=“#thePassWord#”, port=“#thePort#”,transferMode=“binary” );
cfscript

did you try passive mode?

Hello Zac,

Yes I’ve tried that… I’ve also tried transforMode = “Auto”

Can you double check that? I was able to replicate the error using a standard unencrypted FTP connection on port 21 with transferMode="binary". But when I changed to transferMode="auto" the connection succeeded.

This was on Lucee 5.3.4.85. Which version are you using?

I was able to solve my issue by removing the Attribute, transferMode=“binary”.
I think transforMode = “auto” would also work.
