failed to connect calamari to ceph node

After running the command `sudo calamari-ctl initialize`, I visited the website of calamari.
It showed "This appears to be the first time you have started Calamari and there are no clusters currently configured.”
I ran `ceph-deploy calamari connect ceph1 ceph2 ceph3` and the information is all right like this:

However, when I visit the website of calamari, it still shows that This appears to be the first time you have started Calamari and there are no clusters currently configured. How should I fix this? Thank you.

Start by reproducing `sudo calamari-ctl initialize` and `ceph-deploy calamari connect ceph2 ceph3`, then inspect the Calamari and Salt status or logs to determine why the nodes are not registered. Done means the connected Ceph cluster appears in the Calamari website instead of the first-start message.
