3742.322 (9) ERROR: Google Drive upload error: Operation timed out after 15001 milliseconds with 0 bytes received (line: 81, file: /home/claimsma/public_html/wp-content/plugins/updraftplus/includes/Google/IO/Curl.php)
This means that there was a network connectivity problem in between your webserver and Google Drive. It may be only temporary - so, you should try again and see if you get the same error. If you do, then you'll need to show it to your web hosting company, so that they can check on their connectivity from the server that your website is on.
Best wishes,
