Most of the time, FTP connection issues are caused by firewalls or incorrect settings in FTP software. The below steps will help you resolve these issues.

We are often met with resistance by customers who don't want to perform these steps because a given connection may have worked in the past but isn't working now. In our experience, the change that caused the problem is usually on the customer side, and that's why we'd really like you to go through and verify all of the following things before asking us for further help.

If we end up performing a Zoom call together to troubleshoot, these steps are exactly what we will investigate together.

• Local network / firewall issues
• Connection settings in your FTP app
• FTP connectivity issues
• FTP configuration on Files.com that may be relevant
• FTPS Certificate Information
• Partially uploaded files
