Ncp user login no response

I use the nextcloudpi docker on the Raspberry Pi 4,

sudo docker run --detach --publish 4443:4443 --publish 443:443 --publish 6080:80 --volume ncdata:/data --name nextcloudpi ownyourbits/nextcloudpi-arm64:latest

And I activated nextcloud, but I opened and entered the user name ncp, and the password xOy2f71r + JAwX3OwLKypNcaI + tGFp + MygwFUJrnHbY4; the page no response,login failed

Not sure why it happened. But you can change the password in the ncp-config / IP:4443. So if you change it there it should work. If not something bigger is going on
