After deploying to an Azure environment the following error message is thrown when attempting to access or log into the site.
Page could not be loaded
The link you specified does not work. This may either be the result of temporary maintenance or an incorrect link.
This error is often thrown when multiplexing is set as the default providers are set to multiplexing, which is not supported within an Azure environment. Often changing the default providers results in the ability to access and log into the site. Bellow is an example of the settings within the web.config which have been associated with this error.
<membership defaultProvider="MultiplexingMembershipProvider" userIsOnlineTimeWindow="10" hashAlgorithmType="HMACSHA512">
<roleManager enabled="true" defaultProvider="MultiplexingRoleProvider" cacheRolesInCookie="true">
