FTP Update Issues

I use a FreeNas server to hold our updates, if I use an FTP Client like Filezilla, I can upload and download the files without issue. However, if I use WyUpdate, it works around 30% of the time, and generally only when the update is small. For larger updates, around 90Mb, it starts the download, seems to be downloading the actual updated files, gets pretty close to the total size, then jumps to the end, then gives an error says is failed Adler32 validation. I am taking this to mean the file didn't download correctly.

Can you please tell me what ftp client you are using, and what settings, so I can try to figure out what is happening.

Thanks

Use SFTP (SSH FTP) for uploads and HTTPS for downloads.

Everything else is putting your data at risk. FTP is a dead technology (or should be).

Not really a helpful answer. Your product says it supports FTP. I have hundreds of clients with the program hardcoded to use FTP, as your documentation describes, I have no way of changing them all, as they can't currently pull any updates.

Can you please just provide the information I asked for instead of critising my choice of technologies, afterall the choice was made based on what your documentation says it supports.

Much more information is needed. Since you didn't provide it (error codes, versions, reproducible examples, etc., etc., etc.) I provided the quickest solution: use better protocols.

If you want help with the existing protocols, you need to provide enough information: https://wyday.com/limelm/help/faq/#useful-reports
