Infscape Appliance for Raspberry Pi 4: Error 503 with "Access server web shell" and "Access web server data (netdata)"

Hi there,
I work with the most recent appliance, kernel 5.10.60-20210825-ge4cb65cf23c7-p4-bis .
“Access server web shell” and “Access web server data (netdata)” yields both: “Error 503: Service Unavailable. The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.”
How to fix these two issues? Thanks in advance.

The appliance system upgrade from 1.10.4 to 1.10.6 fixed both issues. So accessing netdata dashboard and accessing the web shell works now.
