FTP Connection issues

[Gregoric]

Hello,

I have stumbled upon a weird issue with FTP connection to my account on Gigarank. Out of nowhere, yesterday, the connection stopped working properly. I am using Notepad++ (NppFTP addon), HippoEDIT and FireFTP. Connecting works fine (seems so, at least) but when the root folder contents are about to be listed, the two latter of the applications above just freeze or simply attempt to receive the catalog list but fail to do so.

Notepad++ is rarely able to list the root shared account folder (it succeded twice today, quite randomly), as it returns Failure retrieving contents of directory / . However, I have a separate NppFTP profile that has a path set to one of my subdomains' folders. It is able to easily list the folders within that particular subdomain catalog but nothing more when trying to open any of folders.

I have been using OpenDNS DNS servers, turned them off as some port may have been blocked, flushed DNS; that did not help. Changing between active and passive modes did not help either. Resetting NppFTP configuration did not help. I have also tried to disconnect all my connections via cPanel - did not really help.

Should I do some ping or traceroute or anything that would help troubleshoot this problem? Also, when I am connecting to a different server, everything works fine. I have been recently playing with Cloudflare on one of the domains, so although it was a day or more before the problems started, that may be a hint.

Below I attach logs, one of NppFTP's connection with passive and other with active connection setting.

Thanks and a bunch of regards!

You may need to lower your simultaneous FTP connections.

I have checked if i can connect from a different host but it's unfortunately no different - http://pastebin.com/raw/jSu1YVDd

About the simultaenous connections - I have only one connection most of the time. Also, as I have mentioned, I have also tried disconnecting all the connections via cPanel and reconnected - it did not help. At the moment, I do have only one connection. At least I think so, that's how does my cPanel subpage looks like:

I think it could have something to do with me trying to do some Cloudflare magic. Right now I think it is completely turned off for all the domains but I am not completely sure. Where could I look for some tips or what should I try to google for? I do not really have any idea so even a small suggestion could help.

Thank you.

EDIT:
Not sure why, but everything seems to work fine now. I haven't really changed anything but somehow it got resolved. If it's magic done by you, un4saken, my thank for you, have a good day

Edit: post is out of date again. Everything got back to normal after 3 days of not being able to connect. Again, if it's you, un4saken, thank you a bunch!

Well, hello, again.

Completely not sure why, but the issue has appeared once again. All the symptoms are the same, here's Notepad++ log:

[NppFTP] Everything initialized

Is it that my IP has been restricted from accessing FTP because of too many connections? I do connect only using Npp, so that's like one or at most two concurrent connections. I do check in my cPanel if there aren't any more but mine is the only one active.

Any idea why this may have happened? Maybe Npp bugged out and tried multiple connections at once and I should ismply change program I use to connect to FTP?


My regards

Can you please try another FTP client?

I did actually try Notepad++, CoreFTP, HippoEdit and FireFTP. Later I did try to connect from my workplace using CoreFTP and Notepad++. Result was always the same for 2-3 days and later, out of nowhere, everything came back to normal.

Again, I've always checked if there aren't too many FTP connections, but there weren't. Still no idea what caused the issue - may it have been some kind of served-side blockade caused by accidental too many connections being made?

I've been waiting if the issue appeared happened again but it did not, everything seems to work perfectly fine

If I may ask a little offtopic-ly: is it possible to use encrypted connection to FTP - and if yes, should it be SFTP or FTPS and at what port?

Regards!
