I have been connecting to a ftp server for some time now, but it has stopped working this week.
The connection to the ftp works fine when accessing through FileZilla Client. But not when I try to go through R or internet explorer (both was working untill now). I have made sure that no firewalls are blocking the access.
I am using the Rcurl, getUrl functions to retrieve the data.
When I compare the output in R with the output log from Filezilla, I can see that both succeed in logging in, then run the PASV command. But since the PASV is diabled, filezilla manage to run the PORT command and collect the data.
From Filezilla log: 2017-08-07 13:57:02 2372 1 Command: PASV 2017-08-07 13:57:02 2372 1 Response: 500 PASV command is disabled. Use PORT command. 2017-08-07 13:57:02 2372 1 Command: PORT 10,45,9,89,222,62 2017-08-07 13:57:02 2372 1 Response: 200 PORT command successful 2017-08-07 13:57:02 2372 1 Command: LIST 2017-08-07 13:57:02 2372 1 Response: 150 Opening ASCII data connection for ls /.

Has anyone got good inputs for this issue?
