John, you won’t believe this, but I found out what the problem last night. I’m with this company that pays me so they can monitor my internet use. I have a device that connected to my router. I was on Opera and I was getting the same problem, but Opera happened to show a certificate from that company. A few moments after I disconnected the company’s device from the router. Every issue I had since November 2022 is now resolved. The Itunes is finally working, Microsoft office is syncing, including the recent issue. Thank you for your time and patience! I really do appreciate it.
