0 asset files were found error

After checking files in the asset optimization section, I get the following message:
“We’ve completed the file check but haven’t been able to load the files. Please try clearing your object cache, refresh the page and wait a few seconds to load the files, or visit your homepage to trigger the file list to show. If you continue to have problems, please open a ticket with our support team.”

I tried clearing my cache but it didn’t work
Kindly help
Thanks
