However since the past few days I have started getting the below error while establishing connection
url <- "https://selectapi.datascope.refinitiv.com/RestApi/v1/Authentication/RequestToken"
b <- list(Credentials=list(Username=jsonlite::unbox(uname),Password=jsonlite::unbox(pword)))
r <- httr::POST(url,add_headers(prefer = "respond-async"),content_type_json(),body = b,encode = "json")
Error in curl::curl_fetch_memory(url, handle = handle) :
schannel: next InitializeSecurityContext failed: SEC_E_ILLEGAL_MESSAGE (0x80090326) - This error usually occurs when a fatal SSL/TLS alert is received (e.g. handshake failed).
