Server Api connection string about rblpapi HOT 3 OPEN

Are you sure you're connecting to the SAPI server? The specification you're using for the host parameter seems likely to end up on your local machine, which would be a desktop API instance.

Could you possibly paste the exact console input/output? That might be helpful.

I usually don't have an issue with using the DAPI .

It's hard to know for sure, but you may be getting tripped up by setting isAuthId = TRUE. From the docs:

isAuthId A logical indicating whether to interpret the uuid as an authId for authenticating a user with a B-PIPE application.
appName If isAuthId is TRUE, this is a character string associated with the B-PIPE application name. This will be the same appName used by blpConnect(). If isAuthId is FALSE, this will be ignored.

It doesn't sound like you're using B-PIPE, so isAuthId should be FALSE. The error about empty authOptions would be consistent with the wrong value here along with appName = NULL
