# How to fix "key expires\_in " error

This error is caused by incorrect endpoint URLs.

In this case, you should open the app in Azure and copy the first two URLs from the list:

And paste them into Auth endpoint URL and Token endpoint Url, respectively:

<figure><img src="/files/vW3clGdQRTq5rOAO4t6c" alt=""><figcaption></figcaption></figure>

Please keep in mind that Email This Issue can only work with the v2.0 URL, so if you can't see that in the URL(s), the connections won't work.
