Immich using Docker under Unraid

I have installed Immich on my Unraid server using Docker. I've used the instructions from Alientech42. When I start Immich, I get the following error; PostgresError: password authentication failed for user "postgres" at ErrorResponse (file:///app/immich/server/node_modules/.pnpm/postgres@3.4.8/node_modules/postgres/src/connection.js:817:22) at handle (file:///app/immich/server/node_modules/.pnpm/postgres@3.4.8/node_modules/postgres/src/connection.js:489:6) at Socket.data (file:///app/immich/server/node_modules/.pnpm/postgres@3.4.8/node_modules/postgres/src/connection.js:324:9) at Socket.emit (node:events:508:28) at addChunk (node:internal/streams/readable:559:12) at readableAddChunkPushByteMode (node:internal/streams/readable:510:3) at Readable.push (node:internal/streams/readable:390:5) at TCP.onStreamRead (node:internal/stream_base_commons:189:23) { severity_local: 'FATAL', severity: 'FATAL', code: '28P01', file: 'auth.c', line: '323', routine: 'auth_failed' I have confirmed that the password is correct. Can anyone advise a solutions please?
