cannot dial to the fronting domain

[Cooler044]

Hello, I have installed and configured mtg on a raspberry pi.
I have configured it to bind to 0.0.0.0:443 and configured port forwarding for 443 on my router.

I have generated the secret as stated in README. Put it to the config file and to the client.

Every time I try to connect to my proxy i have this warning in proxy log and it does not connect at all:

mtg[630]: {"level":"warn","logger":"proxy","error":"cannot resolve dns names: cannot find any ips for tcp:google.com","timestamp":1637092288600,"message":"cannot dial to the fronting domain"}

I have tried some other domains at secret generation step, but with no luck.
Could, You, please, help me?
Maybe I understood something incorrectly...

UPD:

I turned on debug mode, here is what it outputs (i have replaced ips, ids...) :

Here is an error: cannot resolve dns names: cannot find any ips for tcp:google.com. It means that for some reason DNS lookup has failed
