Png files failed to upload using ftp

[spyshow]

hi

when I am trying to upload my WP from my PC to the htdoc folder using FTP, i noticed that png, scss, and jpg files failed to transfer even they are less than 500 kB

is there a restriction on file type to upload?

Please be more specific than “failed to transfer”

Perhaps it would help if you provided the transfer logs.

How to get full logs from FileZilla

When trying to debug issues with FTP connections, it’s very useful to know what an FTP client is doing under the hood. FileZilla is a very popular FTP client which can provide fairly detailed information about it’s connections. This article explains how to get this information. Enable debug logging To enable debug logging in FileZilla, you’ll need to do the following: Go to Edit → Settings… Scroll down to the Debug page. Ensure that “Show debug menu” is enabled (it is by default). Update the…

This seems that FTP is breaking at the point it’s switching to passive mode. Passive mode is good for almost all clients. However, some routers try to be “smart” and will try to “fix” FTP, and end up breaking it completely because of this.

This article has a few methods that may help:

Help, I cannot connect to FTP

Being able to access your hosting account over FTP is very important to manage your website files. However, there are reason why you may have trouble connecting to the FTP service. This article explains a few things you can try to fix your FTP connection. Login to your control panel After your account has been created, or reactivated after a suspension, you may need to login to the hosting control panel once to enable FTP access to your account. You can login to the control panel by logging in…

The FTP ALG section in the article would be the best way to solve it. Alternatively, you could try to connect over a VPN instead to bypass your router messing with the FTP connection.

I completely agree. Please configure FileZilla to use “FTP over Explicit TLS” instead. You can configure this from the Site Manager (found under the File menu in the top bar). The Quickconnect will try to determine the best setting by default, which should be explicit TLS. But if there is a router or firewall in between that’s hijacking your FTP connection, your FTP connection may not be secure.
