By sending email the generated URL isn`t correct Forgot password module

Hello Team, I`m using the app store module Forgot password to register customers. By confirming the pending customer request I receive the following message ‘The url you have open seems to be invalid or it is already used.  Please validate the link or request a new password. ‘ The option forgot password works correct. The both options (confirm pending requests and forgot password) use almost the same flows. How to fix this bug?

this could be multiple things. There might be double slashes in the link. Or the configuration is not correct, for example not allowing guest users. 

Can you provide some more information? What did you already check to solve this?
