You don't say whether you are getting this error from the Apple Mail App on an IOS device but the "No password provided" error seems to crop up a lot there often for no apparent reason.
However, one thing might be worth trying:
Virgin Media have recently made another change to their email service which means that when you reset a VM email password you now have to generate an app specific password to use instead or your webmail password when accessing that email address via any third party email apps or clients on all your devices.
So try generating a new email app password by signing into the My Virgin Media account for that Blueyonder email address.
Sign into this link https://my.virginmedia.com/home/signIn using your Blueyonder email address and existing password. That will take you to the relevant "My Virgin Media" account for that email address.
Then click on the "Account settings" tab and then the "Account details" tab. Scroll down that page to "Mailbox app password management." and click on "Manage". You can then generate an email app password which will be in the format: video-post-mossy-sharp
Then go back to email app and enter that new app password (including the "-") into the password field for your Blueyonder account in the email app.
See if that solves the problem.
