We have problem with all existing ssl's and also renewing the expired ssl's is there some global issue with letsencrypt?
One of Let's Encrypt's root certificates expired about 19 hours ago, which could cause issues if things weren't set up correctly. Where are your websites hosted and how do you obtain Let's Encrypt certificates(eg. using certbot, etc)?
We mitigate the issue using the workaround solution provided by cPanel by executing following script
/scripts/autorepair update_lets_encrypt_cabundles
Great, good to hear.
