LoRa distance problems

Hello, i'm using lora ebyte e30-170t27d. I'm trying to send message to receiver and after sending message i wait till response, after short amount of time i get response. The problems is my distance of communication between sender and receiver is too low (i get errors after 100 meters and after 100m i can't receive any answer message). What should i check? i checked antennas and supply voltage. And also i tried to use e220-400t22d - same result (a little bit better, i get errors after 150m i can't receive any answer message). Any suggestions of what to do next? Thank you.
