I am trying to open a remote driver using the RSelenium package with Chrome driver and encountering the following error:
>> library("XML")
>> library('RSelenium')
>> checkForServer()
Warning message:
In order(as.numeric(gsub("(.*)/.*", "\\1", selJAR)), decreasing = TRUE) :
NAs introduced by coercion
>> startServer()
Warning message:
running command 'java -jar "C:/Users/Jessica/Documents/R/win-library/3.4/RSelenium/bin/selenium-server-standalone.jar"'
had status 127
>> remDr=remoteDriver$new()
>> remDr$open() # open web browser
[1] "Connecting to remote server"
Error in function (type, msg, asError = TRUE) :
Failed to connect to localhost port 4444: Connection refused
But it seems that I am having a difficult time establishing a connection.
I think the error message after the startServer() is implying that R is unable to establish a serenium server.
One way I tried to resolve the issue is by copying both the selenium-server-standalone.jar and chromedriver.exe files into the document folder so R can find them. But so far no luck in establishing a server. What am I missing? I appreciate your help.

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've been trying to connect to chrome many times through selenium, however, it always shows the error message below.
I've already check the latest version of my chrome, not sure what's going on :( thanks!

I've been struggling to run an R script on Heroku with RSelenium. I have other scripts running on the platform, but I can't make a Selenium server start. I'm trying it using the help I found
here on stackoverflow. I have Google Chrome and ChromeDriver added to my Heroku slug. I managed to pull up the following code:
eCaps <- list(chromeOptions = list(args = c('--headless', '--disable-gpu', '--blink-settings=imagesEnabled=false',
'--disable-dev-shm-usage', '--no-sandbox', '-Dwebdriver.chrome.driver=/app/.chromedriver/bin/chromedriver'),
binary = Sys.getenv("GOOGLE_CHROME_BIN")))
remDr <- remoteDriver(
browser = "chrome",
extraCapabilities = eCaps
)
remDr$open()
where I have an environment variable GOOGLE_CHROME_BIN storing the path of the Chrome binary as /app/.apt/usr/bin/google-chrome.
When I run the script I'm getting the following error:
[1] "Connecting to remote server"
Error in checkError(res) :
Undefined error in httr call. httr output: Failed to connect to localhost port 4444: Connection refused

I installed docker toolbox to use splashr package in R and followed steps to install splash. But, I am getting an error saying "C:\Program Files\Docker Toolbox\docker.exe: Error response from daemon: driver failed programming external connectivity on endpoint"
Error which I am getting in R is --
"render_png(url = "https://analytics.usa.gov/", wait = 5)
Error in curl::curl_fetch_memory(url, handle = handle) :

Can anybody help me out on this please?
I am trying to use RSelenium, so far I used the below code to initiate the Selenium server on my local computer (on my RStudio IDE) and had no problem.
But I am now working on an AWS EC2 instance on RStudio and the same code does not work anymore so I am a bit puzzled.

Anyone ? Thanks!
