Router Has Bad Cert

I can’t connect to my next gen fiber optic router gateway because the certificate is bad and CCleaner will not let me put it on an ignore list. You have to connect to get a cookie. I can’t connect with the browser, that is. The admin account has a bad certificate. But everything on the computer is very happy to use it as a gateway.

is this a question about CCleaner browser? if so, i can move the topic to the correct place. if not, and this is about CCleaner for windows, as this board is for, I’m at a loss to what you’re referring to.

It involves both. You have to set up cookies in CCLEANER. I’m fine with it if it needs to move

There are a couple of different way to tell CCleaner to leave ceratin cookies alone.
Both methods add cookies that are to be left alone to the same ‘Alllowlist’ so which way you use is up to you:
If you know which cookie it is then you can select the cookie in question and move it into ‘Cookies to keep’:

If you don’t know the cookies name then you may be better using the option in Health Check.
