Why this matters
These protocols are not interchangeable despite similar names.
Step by step
- Check whether the product supports FTP with TLS or SSH-based SFTP and what access has been granted.
- Select the documented encrypted method instead of changing ports repeatedly or disabling security prompts.
- The client should report the intended secure protocol and authenticate to the correct service.
Keep the result of the final check and any unresolved question with your project records.
Availability depends on the product, permissions and management agreement. Use the existing support conversation for the same issue.
