1)Check if the "as-policy.txt" has the correct domain and metaspace
Spotfire Server specifically checks for policy file name as "as-policy.txt" which should be saved at <Spotfire Server Install>\nm\trust" folder and the metaspace should always be "spotfire" and the domain should always be "AS-DOMAIN"
Note the highlighted lines in the image below
2)Only one "as-policy.txt" file is created and copied to each server in the cluster
a)Create the "as-policy.txt" file only on one server in the cluster.
b)Update the metaspace and the discovery section i.e the server ip address and the ports as shown in the image above
c)Copy the above file to other servers in the cluster (In the folder <Spotfire Server install>\nm\trust\) . DO NOT create a new policy file on each server
