When trying to upload an existing website which has never given any problems before I get the Progress window with the message "Cannot complete upload because an operation timed out. [421 Please reconnect using TLS security mechanisms.]
What does this mean and how do I solve the problem?
Hi Alan,
The error message suggests that you need to use a secure upload method, probably FTPS (Secure FTP).
Are you using FTPS or plain FTP?
Plain FTP. I tried FTPS last evening but came up with “Failed to connect” so I think I’m on the right track!
Thanks!
If your hosting provider has support articles on their website or a dashboard for you to log in to, looking in those places for the latest upload details would be a good place to start.
It may be that they use a non-default port for FTPS or they may have moved to SFTP (SSH), for example.
Hi,
I think the error Cannot complete upload because an operation timed out. [421 Please reconnect using TLS security mechanisms.] indicates that your FTP server now requires a secure TLS connection. To solve this problem, ensure your FTP client is configured to use FTPS (FTP over TLS). In your FTP client’s settings, enable the option for secure connections (FTPS or TLS) and try uploading your website again.
Thanks
