I'm having intermittent issues with signing in to LinkedIn with the LinkedIn Sign In API.
By intermittent I mean, I have two LinkedIn accounts, and as of this week one of them is unable to use the API to sign in to external services, such as the LinkedIn application I develop.
I'm authenticating via Auth0, whose engineers have confirmed there is an issue:
Over the last few weeks, the current version of the LinkedIn API for sign-in has been intermittently failing when fetching the user profile, causing a small number of users to fail to log in. The cause of this issue is currently unknown, and is coming from LinkedIn directly.

The Auth0 response i'm getting is the following (I've replaced senstivie response values with 'XX'):
{"name":"a0.response.invalid","message":"unknown error","json":{"error":"invalid_request","error_description":"InternalOAuthError: failed to fetch user profile (status: 500 data: {\n \"errorCode\": 0,\n \"message\": \"Internal API server error\",\n \"requestId\": \"XX\",\n \"status\": 500,\n \"timestamp\": 1550474289966\n})","state":"XX"},"status":0}
I know this API is being depreciated in March, but it's imperative that this API continues to work until the decommission date. I'm wondering if anyone has found a work around or solution to this issue, as it's impacting my ability to run real-world trials of my application scheduled in this week.
I've contacted LinkedIn support who directed me here.
Auth0 recently released a change to LinkedIn social connection, allowing you to use the new LinkedIn API (Version 2). You can change this by going to Connections-->Social-->LinkedIn-->Strategy Version dropdown and select Version 2. This should fix most of the login issues with the old deprecated version of LinkedIn API. More information post.
