Thanks for reaching out to us.

It may relate to the libcurl that the application is using.

The Real-Time-SDK-2.0.6.L1 package contains the libcurl libraries. For example:

Please use the libcurl library from the Real-Time-SDK-2.0.6.L1 package.

Hi @Jirapongse,

Client responded that application does not link to libcurl, only refinitiv libraries have a dependency of libcurl and attach List Dynamic Dependencies details below.

Below is there full error description

Do you have any suggestion for this?

The API uses libcurl to send an HTTP request to get an access token. It calls the dlopen method to load libcurl.

From the error message, it looks like the libcurl loaded by the API doesn't support the options used by the API. You need to check the version of libcurl loaded by the API.
