Error in the certificate of the avast page?

When you installed Avast Secure Browser (via Avast Free Antivirus), you noticed that you started getting alerts for so-called “certificate errors”, but they were coming from the address “https://browser-update.avast.com/”. Searching for it in Google Chrome shows the 404 error. Has Avast stopped supporting Secure Browser and if so why don’t they fix this error? I hope you read this message.
