I have turned on proxy on over 20 domain names. However, one of the domain names suddenly shows NET::ERR_CERT_AUTHORITY_INVALID on the browsers of Samsung phones. All other domain names have no problem on the same browser on the same phone. Only that one domain name would show the ssl cert error.
When I visited that domain name on other devices like iPhone and MacOS, the websites can be shown without the ssl cert error. The problem only happens on Samsung phone.
The error on the Samsung phone:
How to resolve this problem?
