Hello @Hao.Tang
Please refer to DataScope Product Suite Connection Options + Requirements which identifies the current connection options for accessing DSS i.e. interface(API) with IP.
However, the clients are encouraged to access DataScope products via host-name-based URLs, not IP addresses. This is the recommended best practice as it requires no changes to client scripts or browser bookmarks in the event of a failover of the Production environment to the Disaster Recovery (DR) site.
Hi @Hao.Tang,
It seems that the "RestApi" is missing from the endpoint. The endpoint URL should be:
https://192.165.219.152/RestApi/v1/Authentication/RequestToken
Also, you need to disable the certificate validation in the application.
