While testing the the IPA Volatility Surfaces API , we sometimes randomly get the error message:
"The underlying connection was closed: An unexpected error occurred on a send."
The documentation for the IPA Volatility Surfaces API ( https://developers.refinitiv.com/refinitiv-data-platform/refinitiv-data-platform-apis/docs?content=65116&type=documentation_item ) lists bunch of error messages but it does not list this.
Could you please give more details on this error message?
I can see that you opened case 09098863 with Refinitiv Helpdesk and that the case was closed without resolution. Do you still experience the error? Please let us know either way. If the issue is still outstanding, I'd like to make sure it gets to the right resolver team within Refinitiv.
