If I access the server from another machine on the same local network via the local network address https://www.hivelocity.net/kb/what-are-the-steps-to-resolve-the-error-421-service-not-available-in-case-of-ftp/ (192.168.0.2) it's ok. I also set it up to be accessed from an outside internet address. It's behind a firewall router using port forwarding. It's DLINK 625. I opened the FTP port and have it forwarding to this machine. It worked for a while. The it suddenly stopped. I connect ok and get passed the user and password. Then I tried commands: ls and dir It returned: https://forum.filezilla-project.org/viewtopic.php?t=15359 200 Port command successful but then it hung for a while and then returned this error message: 421 Service not available, remote server has closed connection.I tried it repeatedly with the same result. At the same time I also tried again from another local network address and the dir command worked ok. Is this an internet network problem?Is the server trying to use a second port that I did not open on the router? Do I need to open other ports?Thanks.Eli Top Profile Reply with quote boco Post subject: Re: 421 Service not available, remote server has closed connectiPostPosted: 2010-03-18 01:52 Offline Contributor Joined: 2006-05-01 03:28 Posts: 22710 Location: Germany Quote:421 Service not available, remote server has closed connection.This is not from FileZilla Server, I guess.Please read Network Configuration. _________________### BEGIN SIGNATURE BLOCK ###No support requests per PM!
