I have tried to use a website to check if the port is open, but I get this error: Error: I could not see your service on 84.251.- on port (21) Response: 503 Failure of data connection.īetween the 150 opening and the 503 failure code are several minutes. Response: 220 FZ router and firewall tester ready When I do the filezilla wizard test, I can get almost through if I set to obtain ip-adress from filezillasite. I have already tested to shut off the windows firewall and the firewall of our adsl router, but it did not help. I have Windows 7 with only the windows firewall, I also use Avast but without firewall.

I tried also the other client, Fileduck or what it was, the one with the yellow duck, but I think its not working also, I do not receive any errors, (it does not say anything like in filezilla) but it somehow never stop uploading. This problem is not limited to the one server, on the other server I tried, I get the same error after a while. I have started laptop and filezilla new several times. The strange thing is, I set in filezilla settings, that there is only one maximum simultaneous connection allowed. There was an windows update 2 days ago, but I already recovered it, it did not cause the problem. I did not change anything which could be related to this, in the past few days, nor windows, firewall or filezilla setting. After a while, filezilla gets the answer from server, that too many clients are connected.

Since this morning I am unable to make a update with many files (i try to update the piwikinstallation, requires me to upload about 24mb).
