Why does Mikrotik cut url on hotspot?

Question

Mikrotik

There is mikrotik with incl. hotspot, authorization occurs through a link like 10.5.50.1/login?dst=http://www.example.com/, where dst is the address we want to go to.
And the problem is that if dst is of the form http://www.example.com#SOME DATA , then mikrotik cuts to # and leaves only www.example.com.

Answer 1

there # or / ?
I have a format link

<input type="hidden" name="dst" value="https://тратата.ру/трут/WiFi" />

Answer 2

It is not very clear what exactly and where you are trying to transfer. Maybe add your www.example.com to walled-garden?
