Login Issue on Fatoora Portal (Redirect after OTP)

When attempting to log in to the Fatoora Portal (https://fatoora.zatca.gov.sa) and providing the OTP, the system redirects to

http://einvoice-authentication:8899/auth/saml/SSO

Could anyone kindly guide me on how to properly resolve or work with this issue? @Ankit.K.Tiwari @idaoud
Best regards,

@mhaba please use incognito or try changing browser.

Thanks.
Using incognito in Microsoft Edge worked for me this time.
