Cannot connect to TWS using IBrokers with R

Question

The output of my code:

library(IBrokers)
tws <- twsConnect(port=7496)

Error in socketConnection(host = host, port = port, open = "ab", blocking = blocking) : 
  cannot open the connection
In addition: Warning message:
In socketConnection(host = host, port = port, open = "ab", blocking = blocking) :
  localhost:7496 cannot be opened

I have checked my Global Configurations in the TWS. The port is in fact 7496.

Answer 1

It finally worked.. Turns out the "Enable ActiveX and Socket Clients" checkbox was unchecked. I checked it and it worked.

Answer 2

It also worked for me! Log in to TWS and go to

File/ Global Configuration/ API/ Settings

and chek the ActiveX box
