thanks for the reply. added a _redirects file to the project rather than use the toml file to see if that would get the redirect working. It appears the redirect rule has been accepted but when you directly navigate to a page for example the login page i am presented with the netlify 404 error.
I have used the redirects file in the past for a react project and that works as expected, but in this case it does not appear to be carrying out the redirect
I modified the _redirects file an deployed the site but another issue has occurred that is causing the app to fail.
Whilst try to get this working with Netlify i also created a deploy on Azure, that appears to be working as expected without any additional files or configuration so for the time been i will continue going down that route.
Thank you to the people who have tried to help with this, but it is just far easier to use Azure for this project by the look of it.
