We had this query in the forum before, but I'm still not able to reproduce the issue.
Could you please give me this information:
- Full product name of RUT9 router you're using
- Have you tried clearing your browser's cache and cookies?
- Have you tried resetting the device and doing it again?
- When you download the backup, what is the extension of the file? Is it tar.gz?
- Could you please upload a good quality screenshot of the error you're getting?
