Running the below CURL command for a sanity check to see if the TDV Web Manager is responding also returns the same error message:
CURL command:
curl -X PUT -u username:password "http://server:port/rest/v1/session" -k --verbose
Example:/data/TIBCO/TDV_Server_8.4/bin]$curl -X PUT -u admin:password "http://localhost:9400/rest/v1/session" -k --verboseOutput with the error message:

Resolution
(1) Navigate to [TDV_Install_dir]/apps/server/webapps and execute 'ls -ltr' to check the user and user permissions on all the folders/files included in this directory"
(2) Check if all the folders/files in this directory have the same user that was used to install the TDV in the first place. The error "Service Unavailable" we see, is generally when a few of the folders/files in this directory have a different user than the installed user (and permissions).
(3) Change the user on the folders/files with mismatched permissions to match the user similar to that of the other folders/files in this directory.
For example, the below command will change ownership (both user and group) of all files and directories inside of directory and of the directory itself:
sudo chown -R username:group directory
(4) Additionally, make sure the permissions on these folders/files also look similar to the other folder (i.e., irwxr-xr-x)
For example: sudo chmod -R 755 < .path/your_file>
(5) After making these changes, restart the monitor service and open the web manager once the service comes up.
