UpdraftPlus not backing up – error

I have been trying to backup our site to Google Drive forever. It used to work fine but now it will not backup and in the log I am seeing the below error. I have authenticated with Google with no issue:

ERROR: Google Drive upload error: Problem with the SSL CA cert (path? access rights?) (line: 81, file: /home1/bfrevert/public_html/wp-content/plugins/updraftplus/includes/Google/IO/Curl.php)
