UnauthorizedError: invalid algorithm express-jwt

I am displaying some data on my website which returns from node server. It's works perfectly until today. Now I am getting below error on my server console when I go to my web page. I use Auth0 for signin in users.

UnauthorizedError: invalid algorithm

What could be the issue?

Solution

  • I had the same problem. I use Auth0 for signin in users. You have to check the algorithm type.

    If you're using Auth0 then go to

    Client -> Settings -> Advanced Settings -> OAuth

    and check the algorithm type. It has to be HS256.

    If you're not using Auth0 then check the algorithm type also.
