Cannot log-in to rstudio-server

I have previously successfully installed rstudio-server with brew install rstudio-server on a Mac OS X 10.11.4.

Now, I am trying to login to rstudio-server 0.99.902 without success. From the client side, I get a pop-up window saying - >"RStudio Initialization Error", "Unable to connect to service".

The user I am using has an user id of 1100, so I do not think the problem is related to account permissions.

While running the daemon, when I try to log-in, the error showing up in /var/log/system.log is this:

>rserver[1100]: ERROR system error 61 (Connection refused) [request-uri=/rpc/client_init]; OCCURRED AT: void rstudio::core::http::LocalStreamAsyncClient::handleConnect(const boost::system::error_code &) /tmp/rstudio-server-20160803-68705-uhvyws/rstudio-0.99.902/src/cpp/core/include/core/http/LocalStreamAsyncClient.hpp:119; LOGGED FROM: void rstudio::server::session_proxy::(anonymous namespace)::logIfNotConnectionTerminated(const rstudio::core::Error &, const http::Request &) /tmp/rstudio-server-20160803-68705-uhvyws/rstudio-0.99.902/src/cpp/server/ServerSessionProxy.cpp:308

While running sudo /usr/local/bin/rserver --server-daemonize=0, when I try to log-in, no error is output to the console but I do get this error on a pop-up window in the browser: Error occurred during transmission.

Additional info:

rstudio-server verify-installation returns too many positional options have been specified on the command line.

Running sessionInfo() from R console:

These two Github issue comments point to the fact that

> RStudio Server doesn't ship with an administrative script on Mac OSX.

This was fixed here.

Updating your rstudio-server should help. Do note that you should brew tap brewsci/base first.
