When you have received a signing request through Signhost, you may need to verify via iDIN or iDEAL. Check here if your bank is listed:

Is your bank not listed? Refuse the transaction and state in the reason that authentication is not possible because the bank can not be chosen.
​
The organization that sent the signing request can now submit a new signing request with a different form of identity verification such as Onfido, Itsme or via SMS.
