After entering your eRaider credentials and attempting to sign in to eRaider Account Manager on a mobile device, you are redirected back to the sign-in screen in a continuous loop. 

The eRaider system was not able to authenticate your sign-in attempt based on the sign-in key and IP address returned for verification. This could be because your IP address changed.

This problem can also be caused by using an incorrect link to access eRaider Account Manager. For example, if you search Google for "eRaider Account Manager", the first result leads to the link https://eraider.ttu.edu/manager/pages/index.aspx, which is not a supported way to open eRaider Account Manager.

1) Use the correct procedure to sign in to eRaider Account Manager.

2) If the previous step didn't solve the issue, try connecting to the TTUnet VPN.

3) If you still cannot sign in after connecting to the TTUnet VPN, keep the VPN connection active and try opening another site that uses eRaider authentication (for example, https://raiderlink.ttu.edu). Sign in to that site, and then browse back to https://eraider.ttu.edu.

4) Lastly, try using a different Internet service provider (ISP).

Outcome

You can access eRaider Account Manager on your mobile device.
