Letsencrypt SSL Certificate issue in Hosted domain names

" Connection not protected "

From 1st October 2021 all our hosted domain names in the server are showing Connection not protected error message. We tried to renew some ssl from the CWP pro panel but it was not renewing at all. Any one have the same issue or can you suggest me a resolution for this issue.
