'Unable to send transaction - Unable to calculate fee for delegated transfer: HTTP 451' error when trying to send assets
'Unable to send transaction - Unable to calculate fee for delegated transfer: HTTP 451' error displayed when trying to send assets in FinTap app, resulting in no option to complete a transaction.
Cause
Generally, HTTP 451 is the error status code of the HTTP protocol displayed when access to a resource which cannot be served for legal reasons is requested. For example, access to a web page censored by a local governmental authority.
In FinTap app, the error is caused by lack of Know-Your-Customer (KYC) verification, which is the legal reason for a transaction to be denied by the system. This can happen due to one of the following reasons:
- Total abscence of KYC verification, or
- Lack of the next KYC verification tier when exceeding current KYC tier limits.
Diagnostics
Check the status of your KYC verification in the app:
- Launch FinTap app;
- Switch to the Settings tab;
- Check the Personal information section.
Solution
To eliminate the cause of the error, complete the next available tier of KYC.
Once done, re-check the verification status.
