Hello @prashantd

About your "We tried both 'nslookup' and 'curl (version 2)' given by you, and we are able to connect from our network without any error." message, did you try it on the same OpenShift container or the local machine?

Can you try the following Java Code on the OpenShift platform to verify that a simple Java HTTP request can make a connection to the RDP API Gateway?

HttpRequest request = HttpRequest.newBuilder()
    .uri(URI.create("https://api.refinitiv.com:443/auth/oauth2/v2/token"))
    .header("Content-Type", "application/x-www-form-urlencoded")
    .method("POST", HttpRequest.BodyPublishers.ofString("client_secret=<client_secret>&client_id=<client_id>&grant_type=client_credentials&scope=trapi"))
    .build();

HttpResponse<String> response = HttpClient.newHttpClient().send(request, HttpResponse.BodyHandlers.ofString());
System.out.println(response.body());

Note: According to the RTSDK Java README file, the SDK isn't qualified on the Docker platform. If you find any problems while running it on the Docker platform, the issues must be replicated on bare metal machines before contacting the support team.

Does the problem occur on physical machine?

Hello @prashantd

The error message "RestReactor ... failed to submit authorization request, exception = Remote host terminated the handshake" indicate that the API cannot establish a HTTP connection to the https://api.refinitiv.com:443/auth/oauth2/<version>/token endpoint.

Does your company has any firewall or network policy that blocks a connection to api.refinitiv.com domain?

You can try the following commands to verify a HTTP connection from your container/machine.

nslookup api.refinitiv.com

Or if you are using the Authentication Version 1 (Machine ID: GE-A-XXXXXXXX-X-XXXX)

curl --location --request POST 'https://api.refinitiv.com/auth/oauth2/v1/token' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--header 'Authorization: Bearer ' \
--data-urlencode "username=<MACHINE_ID>" \
--data-urlencode "password=<PASSWORD>" \
--data-urlencode 'grant_type=password' \
--data-urlencode 'scope=trapi' \
--data-urlencode 'takeExclusiveSignOnControl=true' \
--data-urlencode "client_id=<APP_KEY>"

Or if you are using the Authentication Version 2 (CIAM, Service Account, Client ID: GE-XXXXXXXXXXXX)

curl --location --request POST \
  'https://api.refinitiv.com:443/auth/oauth2/v2/token' \
  --header 'Accept: */*' \
  --header 'Authorization: Bearer ' \
  --header 'Content-Type: application/x-www-form-urlencoded' \
  --data-urlencode 'client_secret=<CLIENT_SECRET>' \
  --data-urlencode 'client_id=<CLIENT_ID>' \
  --data-urlencode 'grant_type=client_credentials' \
  --data-urlencode 'scope=trapi'

Note: The static IP address of api.refinitiv.com are as follows:

• 75.2.0.254
• 99.83.242.11

Hi wasin.w,

Thanks for the timely response. We tried both 'nslookup' and 'curl (version 2)' given by you and we are able to connect from our network without any error. This handshake issue is happening only on the OpenShift container (Red Hat Enterprise Linux 9.4). Below are the detailed logs from the OpenShift container. I have masked our proxy server details with http://xxx.xx.xx.xxx:xxx so please ignore that:
