LND container throwing error

I have installed umbrel in an ubuntu server.
Running bitcoind in 8332 port, but getting the below error from the lnd container
error creating wallet config: unable to create partial chain control: invalid http POST response (nil), method: getblockhash, id: 1, last error=Post "http://10.21.21.8:18332": dial tcp 10.21.21.8:18332: connect: connection refused

Is there any way to change the port from 18332 to 8332 in lnd container?

maybe the .env file in the the ~/umbrel folder?


is my .env file details
