I receive the ftp socket error 10054 when I try to connect to FTP for an upload. Please fix this problem. That was a recent support ticket received from one of our customers as part of our Dedicated Support Services. This FTP error occurs when the existing remote connection is forcibly closed by the remote host. Today, let’s see the top 6 reasons for the ftp socket error 10054 and how our Support Engineers fix them. FTP socket error 10054 – A Brief explanation A socket is the endpoint of client-server communication. FTP socket error 10054 indicates that the remote host has forcibly terminated or reset the existing connection of the FTP client. And, users see the complete error message as shown below. Upload failed.Socket Error # 10054Connection reset by peer. This broken connection can be at the FTP server side or at the user’s side. So, our Support Engineers primarily check the server logs to determine if this is a network error at the client side or at the server side. FTP socket error 10054 – Reasons & Solutions Now, let’s see the main causes of this error and how our Support Engineers rule out each possibility to fix this problem. 1) Remote server issues FTP socket error 10054 can occur due to the problems at the remote server end. This error usually occurs during the following scenarios. The remote host is suddenly rebooted or restarted. Network interface of the remote server is disabled. User’s account on the remote server is disabled or restricted. Too many users logged on to the server. How we fix? Firstly, our Support Experts check the availability of the remote host using the ping command. ping test.remotehost.com In addition to that, we check the uptime of the server to verify that a reboot has been initiated on the server. uptime Thus, we can confirm whether the server reboot created problems for the user. Moreover, we ensure that the network settings on the server are intact and the FTP user is allowed to connect to the remote host. 2) Invalid FTP host Once we’ve confirmed that there are no issues at the remote host, we then check the FTP client settings. And, one of the common reasons for this error is the use of invalid FTP host address. Users should enter the hostname details in the FTP host field to initiate a connection. For example, customers usually give it as ftp.servername.com or servername.com. However, a typo in the FTP hostname or missing hostname field can result in this error. Even a single additional space in the FTP hostname can create problems. How we fix? Firstly our Support Experts confirm the DNS connectivity of the FTP host using the dig command. dig ftp.servername.com Further, we double check and confirm that customer is using the correct FTP host address in their FTP client. 3) Firewall restrictions Similarly, firewalls can act up and break the FTP connection. Moreover, Antivirus or Antispyware tools can act as a second layer
