Hi, recently I setup a home server for my local lan. Through the use of AdGuardHome and Nginx Proxy Manager, I have attempted to redirect websites I wish to avoid (in this case adult websites). The problem is that Firefix gives the error code MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT and won't allow me to create an exception. As an example, i've tried redirecting google.com to duckduckgo.com. I've looked up solutions to this but nothing has helped. Thanks
