Is this a recent change?  I am having similar issues and can not use my Lacerte software since 2/3/21.  I have always used comcast for internet service and never had an issue.  We did recently upgrade to xfi complete and installed the gateway.  As a test, we re-connected our previous modem and router (that had no issues) and I am still having the same program issues.  I tried to disable protected web browsing but do not see it in our account.

Any suggestions?  I have been waiting for a callback from Lacerte support since Saturday regarding case #559125297.  Please help, I am out of business!
