LinkedIn Error 401 after connection

Hello, I try to connect to my app on LinkedIn, but I get error 401.
The first error was about “The redirect_uri does not match the registered value”. I added it to my app redirect_uri -

Now I get the error “Status Code Error: 401”.


Same issue here… did you find any solution?


I have a slightly different Developer Application URN and a Scope item, but also cannot log onto LinkedIn. I have also generated a new token (secret key) but that too does not solve the problem.
There isn’t much else one can do is there?
