I can access, read and download from host via FTP, but can't upload file.

I tied to use Transmit (on Mac) and Filezilla also, but no success.

Then tried same on different host and got same problem.

Here is the screen of error:

I tried also PASSIVE mode on FTP client, and viceversa, but again not solved.

I know this is probably the first thing you checked.. but your username/password for the FTP Server have Write Access? Oh, and have enough space left for you to upload more files? – Darius May 25 '13 at 15:37
Yes I checked this all, but everything is ok. It's working in windows CuteFTP or Filezilla or other FTP clients. I got problem only on Mac based FTP clients. – zur4ik May 26 '13 at 6:49

It sounds like the account you’re using doesn’t have Write access to the server, you need to confirm that with the server admin.

Account has write access because, when I use it with Windows based FTP clients, it's working properly. I get error on Mac based FTP clients. – zur4ik May 26 '13 at 6:51

After long time searching of solution finally found a solution.

Problem is caused by macs MTU settings:


Put: MTU:1400

Finally FTP transfer is working properly.
