TIBCO Spotfire Server fails to start due to Active Space certificate expiry

TIBCO Spotfire Server fails to start and returns below error in "server.log"
-------------------------
"java.lang.RuntimeException: com.tibco.as.space.ASException: SYS_ERROR (security_config_error - Domain credential invalid: Id time validity error [/CN=AS-DOMAIN-XXXX] [valid after: MONTH datetime"
-------------------------

For secured ActiveSpaces resources, when ActiveSpaces is deployed and configured a token file is also copied to the <Spotfire server\install>nm\trust folder.
This token has a validity period and the above error is caused when the security token expires.

Run the "create security_token" command to create a token file.

1)Syntax to create security token command:
    a)Open a command window and then open the ActiveSpaces command-line interface (CLI) by entering the following commands:  
       cd ActiveSpaces installation dir/as/2.2/bin
    b)Run as-admin 
    c)Run create security_token domain_name <string> policy_file <string> [create_identity [common_name <string>] [encrypt <boolean>][validity_days <integer>]]token_file <string>

Example:
as-admin> create security_token domain_name "AS-DOMAIN" policy_file "C:/tibco/tss/version/nm/trust/as-policy.txt" create_identity common_name 'CN=AS-DOMAIN-B1DD26D6' encrypt true  validity_days 90 token_file "C:/tibco/tss/7.11.0/nm/trust/mytoken.txt"

2)Copy the token file to all the servers in the cluster -  folder "<Spotfire server install>\7.x.x\nm\trust\"
3)Restart the Spotfire Server service https://docs.tibco.com/pub/activespaces/2.2.0/doc/html/GUID-9AF67DD2-BCDE-4806-8D4F-319714523D2C.html?scroll=GUID-9AF67DD2-BCDE-4806-8D4F-319714523D2C
