I am getting certificate errors for websites that were working yesterday

Let’s Encrypt’s DST Root CA X3 expired in September 2021, however, all cached certificates should have expired by now.

If you are still having issues with these sites in your deployment, you may need to update your Netsweeper Certificate Bundle.

If you are not sure how to do this, or would like some help and guidance, please reach out to the Netsweeper Support team by emailing support@netsweeper.com, submitting a ticket through your Community Portal account, or by phoning the support-number for your region.
