Hi, I have experience "unknown issuer problem" for 3 months in only Youtube and Google. I was solving this with some regedit changes and every time I open my computer I have to change the value of one property in regedit. But I formatted my laptop and I cannot find where the property is. I tried to make "security.enterprise_roots.enabled" true and it solves my error problem but now Google and Youtube extremely slow and sometimes Youtube just keep loading for forever. I can accept to find the regedit property. I don't want to change my browser but if the issue cannot be solved, I have to. Thanks.
