    Hello!

    I'm trying to log in to my account. Using my email and password correctly it then asks me for an authentication code sent to my email, I place it and click on "Verify" but nothing happens.

    Then on the JS console I see some CORS errors:

    ```
    Access to XMLHttpRequest at 'https://eu-api.jotform.com/user/login' from origin 'https://eu.jotform.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
    ```

    Attaching a screenshot:

    Hi Ivan,

    Thanks for reaching out to Jotform Support. I'm an AI assistant. I'll do my best to help you until someone from the support team is available.

    The CORS error you are encountering during login is related to browser security policies that block requests when the server does not include the proper 'Access-Control-Allow-Origin' header. This issue can prevent the authentication code verification from completing successfully.

    Unfortunately, this is a technical issue on the server side that cannot be resolved from your end. However, here are some steps you can try to work around the issue:

    1. Clear your browser cache and cookies to remove any corrupted session data.
    2. Try logging in using a different browser or an incognito/private browsing window to avoid extensions or cached data interfering.
    3. Ensure your browser is up to date as outdated browsers may have stricter CORS policies.

    If these steps do not resolve the problem, it is likely an issue that our technical team needs to address on the server side.

    Let us know if you have any other questions.

    Give it a try and let us know how it goes.

    I tried from an incognito window and received a 429 back...

      8615.75426e0e.js:1  POST https://eu-api.jotform.com/user/login net::ERR_FAILED 429 (Too Many Requests)


    Will try again later

    Hi Ivan,

    The 429 error you received indicates that too many login attempts have been made in a short period, which triggers a rate limit to protect the system. This is why you are seeing the "Too Many Requests" message.

    At this point, the best course of action is to wait for some time before trying to log in again. This cooldown period allows the rate limit to reset.

    If you continue to experience issues after waiting, please let us know, and we can explore further options.

    Give it a try and let us know how it goes.
