Network connectivity test
When running a connectivity test, I get this error:
TCP Connection: unblock DNS for URL: ***-myfiles.sharepoint.com. Test FQDN(s) users were ***-myfiles.sharepoint.com
Stars replace our company's prefix to our SharePoint site.

- I found that they are being listed as required at https://aka.ms/o365ip under ID 39 now. I think Microsoft is planning to use them soon.
Never heard of that URL before i.e. 'myfiles.sharpoint.com'
Just some random ideas...
Have you got the latest version of the https://www.microsoft.com/en-us/download/details.aspx?id=103017?
Do you get the same error in the https://connectivity.office.com/?
The tool has a config file, has this been modified? Try with default config.
Good luck.
The only domains I know of is:
- <initial_domain>.sharepoint.com - Regular SharePoint sites
- <initial_domain>_my.sharepoint.com - OneDrive for Business
They both resolve fine for me. Try to specify "-Server '1.1.1.1'" maybe?
Documentation on relevant domains:

- I have the same issue. When I open Powershell and "Resolve-DnsName ***-myfiles.sharepoint.com" (replace *** with my tenant name), it responds that the DNS name does not exist. Same with ***-files.sharepoint.com.
