![]() ![]() In such cases, our Support Engineers help users to increase the Timeout values in their FTP clients accordingly.Īlternatively in some cases, we completely disable the Timeout value by setting it’s value as 0.Ĥ) Intermediate firewall or routers block Passive ports In other words, when users upload a large file, then the upload process may fail if it’s not completed within that predefined connection timeout limit. And, this problem is related to the internal timeout settings of the FTP client. Usually, FTP Read Timed out error can occur when users try to upload a relatively large file. We always recommend users to enable Passive mode as the default option in their FTP clients. And, we help users navigate their FTP client settings and enable Passive mode. So, our Hosting Engineers first get the FTP client details used by the customer. The solution here differs based on the FTP client software used by the users. We’ve seen cases in which users have accidentally set their FTP mode to Active, resulting in FTP Read Timed out errors. Instead, it tells the server on which port it listens, and the server connects back to the specified port.īut this connection appears to be a cyber attack from the client side firewall, and hence it blocks such non-standard connections. In Active mode, the FTP client doesn’t make the actual connection to the server. However, active mode requires users to configure their PCs to connect to standard ports from the server. 2) FTP client set to use Active modeĪnother common reason for this error is that users enable Active mode in FTP client to transfer the files.įTP transfers can happen in Passive and Active modes. Here, xxxxx is the starting port, and yyyyy is the ending port in the Passive port range. iptables -A INPUT -p tcp -match multiport -dports xxxxx:yyyyy -j ACCEPT PassivePorts 49152 65535įinally, we open these passive port range in the server firewall.įor example, in a Linux server, we open the passive port range in firewall using the below command. ![]() Secondly, we verify that the Passive port range is specified in the FTP configuration file.įor example, in a ProFTPd server, we un-comment the following directive in the configuration file /etc/nf to specify the Passive port range. And, if it’s not specifically set to access connections on Passive FTP ports, the incoming connections fail.Ĭonsequently, users see FTP Read Timed out error.įirstly, our Hosting Engineers confirm that the connectivity to the standard FTP ports 20 and 21 works well using the below command. ![]() ![]() In addition to that, the FTP server should accept connections to Passive FTP ports which vary from server to server.īut, the problem is that most servers accept connections only on standard ports. The standard FTP ports are 20 and 21, and these ports should be opened in the server for proper functioning of FTP. 1) Firewall blocking Passive ports in server Let’s now see the main reasons for FTP read timed out error and how our Server Support Engineers fix them.
