private relay not working

Hi garpar,

Welcome to Apple Support Communities. We understand that you have questions about using iCloud Private Relay and BitDefender.

About iCloud Private Relay has some information that can help with this. As mentioned in the "If a website or network doesn’t work with Private Relay" section, "Some websites, networks, or services may need to make updates for Private Relay, including networks that require the ability to audit traffic or perform network-based filtering—such as business or education networks—or services that rely on viewing your browsing activity, like parental controls or some “zero rated” services that don’t count against your data usage."

This support article also mentions "If a website, network, or service you're using doesn't appear to be compatible with Private Relay, you can temporarily turn off Private Relay in iCloud settings."

For additional questions about compatibility, we'd recommend contacting the developer: Consumer Support - Bitdefender

We hope this helps.

Cheers!
