Talend Data Stewardship Installer for on-prem and Hybrid version could not redirect the gateway.url to correct host from IAM server or Cloud Server and got error page.
Somehow, it points to localhost instead of the IP Server or HostName specified in the TMC->Configuration->TDS setting.
Resolution
Temporary Workaround
Edit data-stewardship.properties file which is available in <install_folder>\tds\config folder and change gateway.url to correct IP/Host (The real IP of the server on which TDS is installed )
iam/data/client/tds-client.json file also needs to be updated by adding URL item with the correct IP/Host
Final Solution
Wait for new installer versions released after R2025-05
Cause
It is a known bug from Installer level that IP/Host did not be propagated to the config of the Installed version of Talend Data Stewardship.
