Hi @vishwasnavadak,
I don’t think “https://example.auth0.com/user/ssodata” is very chaotic (it’s the same for me , I also get a 404 for it).
What data you got on the 302-http-response to “localhost:3000/callback” ?(is it the same error ,error desc.)
can you share the logs /technical details .
Open Network-tab ( in developer mode/ F12)
In " Request URL:https://example.auth0.com/u/login?…". -with a 302 http
you must be getting Response headers " . what is the value of location key.?
