Failed to read packet and Unable to find registered backend

[alexis-vannot]

Hi guys,

I can't figure out how to block "slowstack.tv" and fix the "Failed to read packet".

There is my .yml

There is the log of mc-router

Thank you in advance for your answers!

Currently there's no way to block any particular backend requests. That would be a helpful feature for your scenario though.
