If I replace todase.smartomato.ru with dostavka-sushi.com then everything is ok.
Also I tried other domains, including other *.smartomato.ru and just *.ru – always getting:
Create new order error. Le_OrderFinalize not found. {"type":"urn:ietf:params:acme:error:unauthorized","status":401,"detail":"A requested identifier is not permitted [<host>]"}
