Re: MYSQLDUMP on remote Ubuntu from Windows 10 now fails with Got error: 2059: "Authentication plugin 'caching_sha2_password' cannot be loaded:

Yes, the credentials are in my.ini.

So something has changed, because now my script and your test both give error 1045 Access denied, even though the correct username and password is supplied, and explicitly as per your test (not rely on my.ini).

Thanks for your help btw.
