Error: Uncaught (in promise): issuer must use HTTPS (with TLS)

Getting console error message when redirecting to Angular SPA Application from okta user account.

Okta Issuer already using HTTPS. Kindly suggest do we need to buy TLS certificate or any option to set TLS in Okta account.

UI: Angular
Package used: angular-oauth2-oidc

Please help.

It sounds like this error is thrown by the library you are using: angular-oauth2-oidc/oauth-service.ts at 3ba7303b5a6fdbae5ca214764c9191637cd00126 · manfredsteyer/angular-oauth2-oidc · GitHub

At least within Okta support, we can’t speak to issues with third party libraries, so you may want to file a Github Issue against this library for advice from the developers supporting it.
