Jake, I did exactly as you said. My only input was passwords for the Mac which I left as "Untitled", the external SSD, AppStore, iPhone etc, but I still cannot connect to AppStore.
Attached are screenshots of the internal SSD. As you will see one is unmounted - I have clicked on mount but nothing happened. All volumes pass the Disk Utility test.

 

[kmbaroyale19]

I have just re-booted from the old SSD which, up until now had always worked perfectly but now I also cannot connect to AppStore. It is now noon here and I have already had enough for today

Your images show that it is properly configured. The Container has the required two Volumes, one named "Untitled" and the other "Untitled - Data." That's how it should be. I would have named the drive, but Untitled is ok, too.

As for the App Store, are you now logged into your Apple ID account? Go to System Preferences and on the top of the pane is "Apple ID" where you can log in. You need to be logged into Apple ID to get to the store.

 

[kmbaroyale19]

I deliberately did not name any volumes. As I said my only input was passwords as and when they were asked for.
I have just re-booted from the internal disk and made screenshots in order of appearance..
I think it was after the second one (22.36.25) I had to enter a code that appeared on iPhone and iPad but I had no time to make a screenshot. The final one is the AppStore screen.
I often get a message that I am not connected to the internet, although I am.

OK, at this point about all I can suggest is to go to Apple.com (or whatever the site is for you), click on Support on the top bar and schedule a tech to call you about the issue. Given that it's a macOS issue, your warranty doesn't matter, so they should be willing to call you. Here in the US the wait times are short, usually minutes, before someone calls you back. Just tell them you cannot connect to the App Store and they should be able to talk you through whatever is going on.

 

[kmbaroyale19]

Thank you Jake, I will try that.
On July 26 I had online chats over a 4 hour period with 4 different Apple Support Advisors. After long sessions of questions and answers each suggested a solution which involved re-booting the Mac, after which of course, they were no longer available.
I have the feeling that when they don't know the answer, they use the "escape" door and tell me to reboot.

 

[MacInWin]

Don't do a "chat" with them, ask for a telephone call. That way you don't lose them on a reboot.

 

[kmbaroyale19]

I have already booked a call for 15:00 tomorrow. I’ll let you know how I get on.

 

[kmbaroyale19]

While waiting for the Apple Support call I decided to boot from the external SSD, however "Old MacBook Pro" cannot be unlocked and Disk Utility is unable to check it. Can things get worse?
I rebooted from the internal SSD and noticed that Dropbox was causing the "no internet connection" message so I dragged it to the trash after which, lo and behold, I could connect to the AppStore. I emptied the trash and the connection was lost again. After a restart it was back - see attachment.
However, the gremlins have not gone away. When I try to scan from my Canon printer I receive the message shown in the third screenshot.
I suspect there will also be problems with permissions on other programmes but, being positive and convinced that everything will turn out well, have decided to cancel the call from Apple Support. I am hoping that you may have the answer - if not, there is still Apple Support.

 

[kmbaroyale19]

Most programmes appear to be working now so I will close this.

If anyone has ideas about the following I would be grateful:
1. Unable to connect to Dropbox - wheel keeps spinning and "no internet connection" message appears.
2. Unable to scan from Canon Maxify MB2750. I suspect this is a Canon problem and unsuitable software for Big Sur. Scanning from iPhone and iPad is. ok.
The above problems have arisen since the issues of the past few weeks.

You are not connected to the Internet. And, maybe not connected to your internal network either, if the scanner is a symptom. Can you get to anything on the Internet from this machine at all? If not, you need to sort out the connection. If you can, then try logging into Dropbox manually again.

 

[kmbaroyale19]

All internet services work perfectly - email, all browsers, all portals connected with my work. Only Dropbox reports “no internet connection”. I’m using my iPad just now because I am on vacation and the Mac is in the hotel but believe me, I have full internet service.

Have a read at these two articles. One deals exclusively with Dropbox/No Internet Connection; whilst the other deals with a MacBook that connects to WiFi but has no Internet connection.

No internet connection

Thank you Ian. I have already seen the dropboxforum post but the answer wasn't there. Because I am not able to connect to DropBox I can't login to change proxy settings as some people suggest.
Obviously I do have internet connection otherwise we wouldn't be able to communicate.
I connect daily to international companies which use high tech encryption.

I'm seriously considering downgrading from Big Sur to Catalina.
What does the Mac-Forums community say?

 

[MacInWin]

Big Sur is better, from my perspective.

I'm seriously considering downgrading from Big Sur to Catalina.
What does the Mac-Forums community say?

Bad move. Catalina had its own problems, many of them taken care of in Big Sur. Downgrading always leads to other difficulties. Our advice is not to do it.

 

[kmbaroyale19]

I finally took the time to contact Apple Support - don't know why I waited so long.
An advisor called Kieran talked me through the process and, with the help of Malwarebytes, we isolated and removed 15 items which didn't belong here. We also cleared 3 login items but we don't know if they were causing a problem and we deactivated the firewall.
Once again many thanks to the Mac Forums Community for sacrificing so much time over the last few weeks.

We rather like "Dummies". That's what we are here for; all of us having been Dummies at some time in the past.

Ian and all members, you are more than kind but, at the age of 74, I have accepted that I will remain a Dummy and am, therefore, especially grateful for your help.
