After updating to RStudio Version 2022.12.0+353 (2022.12.0+353), I am unable to find a freeport using netstat.

I have never had this problem before. How do I fix this?

library(RSelenium) library(netstat) remote_driver <- rsDriver(browser = 'firefox', verbose = F, port = free_port()) Error message: Could not open firefox browser. Client error message: Undefined error in httr call. httr output: Failed to connect to localhost port 14415 after 0 ms: Connection refused Check server log for further details. Warning message: In rsDriver(browser = "firefox", verbose = F, netstat::free_port()) : Could not determine server status.

I have tried:

netstat::free_port() which failed.

I've switched the browser to chrome with no success.

Docker has never worked with my macbook.

    I had the exact same issue @bandcar and even when using a firefox browser you still need to put chromever = NULL and (for me) it worked. Commented Mar 8, 2023 at 23:33
