Spring Security Unable to resolve the Configuration with the provided Issuer of

Describe the bug Hi, I'm trying to set up a resource server that validates ID and Access Tokens from my SPA with Azure Accounts. The issuer-uri that I'm using is https://login.microsoft.com/tenant-id/v2.0/.well-known/openid-configuration. I set up a custom jwtDecoder for verifying incoming tokens inside my security configuration:

@Value("${azure.activedirectory.tenant-id}")

@Value("${spring.security.oauth2.resourceserver.jwt.issuer-uri}")

JwtDecoder jwtDecoder() {
    OAuth2TokenValidator<Jwt> withAudience = new AudienceValidator(audience);
    OAuth2TokenValidator<Jwt> withIssuer = JwtValidators.createDefaultWithIssuer(issuer);
    OAuth2TokenValidator<Jwt> validator = new DelegatingOAuth2TokenValidator<>(withAudience, withIssuer);

    NimbusJwtDecoder jwtDecoder = (NimbusJwtDecoder) JwtDecoders.fromOidcIssuerLocation(issuer);
    jwtDecoder.setJwtValidator(validator);
    return jwtDecoder;
  }

I get the following error: Unable to resolve the Configuration with the provided Issuer of "https://login.microsoftonline.com/tenant-id/v2.0/.well-known/openid-configuration

I'm unsure about the format that is expected for the issuer-uri and don't know which URI to really use (the microsoft docs don't provide any help for this). Is there a sample project that uses maybe a /commons/ microsoft endpoint, so that I can get an idea about the format?

Thank you all Alex
