FTP - 'Operation was aborted by an application callback.' ;-)

Worked fine… now it publishes a few desultory files out of the eight million it has to publish every time I change a single character in a paragraph, and then the rest of them languish in FTP hell with the following ‘information’ note:

‘Operation was aborted by an application callback.’

It also freezes RW with an open FTP transfer notification and I have to force quit. I’ll be honest with you - it’s not ideal.

Any ideas?



Does the 7.4.1 beta fix this for you?


Things seem to be back to normal today, but thanks for the suggestion.


No problem. If it happens again, give the 7.4.1 beta a try - we’ve fixed up a bunch of issues that we spotted with certain hosts and server configurations.

I’m using Version 7.4.1 (18708) and it is still happening.
Are there any corrupt pref files I should be deleting?

I’ve also been having this problem. I’ve been trying to work it out for the past week, but I’ve been unable to solve it. I’ve not been able to update my site for over a week now.

Four days back, I also got Couldn’t upload to your FTP server and then Operation was aborted by an application callback error messages.
I have tried uploading files with small changes and same things.
No changes to the server, I am using RW 7.5.1 and MacS 10.12.6.
Any suggestions please?

I had this problem yesterday when I upgraded to 7.5.1. When I changed my publishing settings from “Active” to “Extended Passive,” uploads started working smoothly again.

I hope this helps you.

I got this clue from reading through the forum discussion. Adjusting publishing settings to “extended Passive” has helped others when they encountered the error message you are seeing following previous upgrades.

Yep, that was a nice thought and I did try it and also passive in case but to no avail. RW won’t back up after attempting to upload -it just hangs soon after it has started.
There are three lines in the one message in fact:
Couldn’t upload to your FTP server
Couldn’t upload to your FTP server
Couldn’t sign in to your FTP server
Checked with the help desk at my server and they checked their end out but no problems they can see. They suggested I do the upload via FileZilla which I will try when I get a moment tomorrow. Seems sad to have to go through an intermediary. RW was going fine until the weekend then this happened. Can’t remember when I upgraded to 7.4.1.

Sorry that was 7.5.1 that I upgraded to.

I’m having the same problem since last Friday and the 7.5 update. Been in contact with the help desk and still no solution. My whole website is currently down.

Is anybody doing anything about your contact with the help desk yet?

I’m having the same problem. I even went as far as creating an entirely new site to test. Nothing seems to be working. Any help would be much appreciated.

I am having the same problem, does anyone have a workaround? appreciate any help.

Days Later and I am still having the same problem you guys are.
Im using Godaddy.com. They sometimes have issues so I thought it was them.
I can publish one page at a time but never get much further than 100 files uploaded till it breaks the FTP connection.
I’ve tested the connection and the ping to google.com is almost the same as to godaddy.com
Have tried everything including making a new site try uploading. Still no luck
I have version 7.5.2 installed
Even tried using Cyberduck to upload to server through FTP connection and it has errors also after it gets started.

I’m getting this exact issue now with Rapidweaver 8.1.7 (20674)…

Host is Fasthosts.

Uploads either random number of files of 70… hangs with ‘operation aborted by an application callback’… Again, have to force quit every time…

I am using RW 8.7 and have been unable to update my website since late Nov 2020. Every time I try to publish (to the same server I have been using for 3 years) I get the message “Operation aborted by an application callback”’ sometimes I also get “Timeout” error as the reason why uploading has failed. Any ideas??

Have the same problem. Upgraded to RW8.7 and now I can’t publish and get the same errors. Trying to figure out what has happened and how to publish my site.

I am seeing the same problem and have posted about it in the German RW forum. It is happening for me with RW 8.7 on a SFTP connection to the host ssh.strato.de. — I have other websites where the SFTP upload to STRATO is working without any issue.

So I would really like to know what is causing this “application callback” problem and what that error message means in particular.

In the meantime I am using a simple workaround: I export my site locally and then sync it with a FTP program (ForkLift) to the server.
