When I attempt download a file from our public FTP server to any of our 3850's I get the below error message.
%Error opening ftp://*****:*****@11.22.33.44/cat3k_caa-universalk9.SPA.03.06.08.E.152-2.E8.bin (Incorrect Login/Password)
I'm using this command syntax to copy the file.
copy ftp://$USERNAME:$PASSWORD@11.22.33.44/cat3k_caa-universalk9.SPA.03.06.08.E.152-2.E8.bin flash:/cat3k_caa-universalk9.SPA.03.06.08.E.152-2.E8.bin
Troubleshooting steps taken...
1. FTP server is pingable.
2. Able to login to the FTP server from my PC using the same credentials
3. Tested using the "ip ftp username" and "ip ftp password" commands and then not specifying creds in the copy command. I receive the same error message.
4. No ACL's on the switches
5. Debug output below
1383852: .May 3 10:14:03.716 EDT: FTP: 220 Serv-U FTP Server v14.0 ready...
1383853: .May 3 10:14:03.717 EDT: FTP: ---> USER $USERNAME

6. We're currently running 3.4.4 on all our switches. There are a few bugs regarding FTP but I don't think any of them would give the symptoms we're experiencing. We do have "ip ftp passive" configured.

As a last resort we can utilize TFTP but I'd really like to get FTP working. We have multiple switches all at different locations with no one on site, so easiest is probably we TFTP over the internet, which I've not had luck with in the past. I'm also just curious why this isn't working.
