When attempting to log in or submit documents to an institutional iThenticate account, you may encounter the following error message:
Error message: E503 Loading Error - The request failed because this item does not exist or is not available to you
Cause
An E503 error on an institutional account indicates a subscription license issue. This typically occurs for one of two reasons:
- Your institution's iThenticate license contract has not yet reached its official start date.
- Your institution's iThenticate account license has expired.
Resolution
Select your role below for instructions on how to resolve this issue:
Individual account holders cannot resolve license dates directly. If you receive error E503 on an institutional account:
- Contact your institution's iThenticate account administrator.
- Inform them that you are receiving error code E503 and ask them to verify your institution's active license status.
If users across your organization are reporting error E503, verify your account's contract dates:
- Check your contract agreement to confirm whether your license start date has arrived or if the subscription has passed its renewal date.
- If your license has expired or needs activation, please contact your iThenticate Account Manager or Sales Representative to renew or activate your contract.
