To configure TabPy, please use the TSM security command here:
I believe you are running into an issue with TSM not knowing whether the connection is secured or not. We always recommend using the commands over the TSM set option because they set all required parameters at once. Let me know if this resolves the issue.
I used the following commands to set the connections
tsm security vizql-extsvc-ssl enable --connection-type "tabpy" --extsvc-host <ip of tabpy host> --extsvc-port "9004" --connect-timeout-ms "1500" --script-disabled "false"
tsm configuration set -k vizqlserver.script.disabled -v false
tsm pending-changes apply
