My third party applications says no_connection error even though I've updated one connection to domain_level

Hi @joe_re,

Welcome and thank you for posting in Auth0 Community!

I apologize for the huge delay in the response.

First, can you please check that you are using the right version of lock?

Can you please try adding the connection to this line?
allowedConnections: connection ? [“YOUR_CONNECTION”] : null,

Please keep in mind that technically it’s possible to get that error even if the application has connections enabled. For example, in the following scenario:

  1. application only has connection CON_A enabled in the dashboard.
  2. application makes use of universal login (hosted login page) configured to use Auth0 Lock as the login user interface.

In the following scenario, if at the hosted login page Lock configuration you set the option allowedConnections to ["CON_B"] then the message in question will be triggered when the application tries to initiate login through universal login because application only has CON_A enabled and Lock is configured to ignore that particular connection which means no usable connections are enabled.

Please let me know if this makes sense and thank you for your patience!
