I am trying (for the first time) to scrape content from a dynamic webpage, for which RSelenium appears to be the go-to. I cannot however get past the first step of calling rsDriver.
My code:
rdriver <- rsDriver(browser = "chrome",
port = free_port(),
chromever = "109.0.5414.25")
The rsDriver() function started throwing an error every time I tried to open it
[1] "Connecting to remote server" Could not open chrome browser.
Client error message: Undefined error in httr call. httr output:
Failed to connect to localhost port 14415: Connection refused Check
server log for further details. Warning message: In rsDriver(browser =
"chrome", port = free_port(), chromever = "109.0.5414.25") : Could
not determine server status.`
Version:
R 4.2.2
Java(TM) SE Development Kit 19.0.2 (64 bit)
> binman::list_versions("chromedriver")
$win32
[1] "109.0.5414.25" "109.0.5414.74" "110.0.5481.30"
> binman::list_versions("seleniumserver")
$generic
[1] "3.141.59" "4.0.0-alpha-1" "4.0.0-alpha-2"`
Any recommendations are much appreciated.
I installed all the necessary programs from scratch.
I searched for help on the internet and couldn't find a solution
there is an outstanding issue with how the wdman package reads the latest versions of Chrome. This is causing issues for lots of users (examples here https://stackoverflow.com/a/75176907/15363011 and here https://github.com/ropensci/RSelenium/issues/264)
You can specify a version of Chrome before the issue took place and binman/wdman will download and start using it:
rdriver <- rsDriver(browser = "chrome",
port = free_port(),
chromever = "108.0.5359.71")
If you'd like to use the newest versions, the fix is to delete the LICENSE.chromedriver file found in the same directory as the driver. You can find out how to do that in the other issues that I linked. If you want to use the latest version of Chrome you will have to do this any time a new chrome driver is released.

Seeking help on how to resolve the subject line error.
The many previous posts and solutions referenced here have already been reviewed/tried.
In the past this same error has been resolved by updating R, Rstudio.
The code, which has worked for years and as recently as few days ago:
library(chromote) # to get the chrome version
library(netstat) # to dynamically change ports
library(RSelenium) # to run Selenium
b <- ChromoteSession$new()
browser_version <- b$Browser$getVersion()$product
browser_version<-gsub(".*/","",browser_version)
realVersion <- substr(browser_version,1,3)
chromeVersions <- binman::list_versions("chromedriver")
chromeVersions <- chromeVersions$win32
realChromeVer <-chromeVersions[which(substr(chromeVersions,1,3)==realVersion)]
driver <- rsDriver(browser = 'chrome', port = free_port(random = TRUE), chromever = realChromeVer[1], verbose = F)
remdr <- driver[['client']]
remdr$maxWindowSize()
Error message:
Could not open chrome browser.
Client error message:
Undefined error in httr call. httr output: Failed to connect to localhost port 3918: Connection refused
Check server log for further details.
Warning message:
In rsDriver(browser = "chrome", port = free_port(random = TRUE), :
Could not determine server status.
Is there anyway to get this running with rsDriver?
I would be really thankful if someone could help me in this problem.
See the answers here https://stackoverflow.com/a/75176907/15363011 and here https://github.com/ropensci/RSelenium/issues/264
The issue is likely that the newest Chrome versions (109+) are creating a bug that is preventing wdman::selenium() from running. Did you try deleting the license file in the chrome driver paths set by RSDriver (via the wdman package)?
I have been using RSelenium for years and have never had this issue. I recently updated my google chrome to the latest version available 110.0.5481.78. I am now getting the following error when I go to use rsDriver
require(RSelenium)
rD <- rsDriver(browser = "chrome",port = 9537L, chromever = "110.0.5481.77")
"> Could not open chrome browser.
> Client error message:

I have tried with different versions of chromever from binman::list_versions("chromedriver") as well as leaving rsDriver blank all together. In the past when chrome has updated it has been a very simple change to chromever and everything works perfectly. Not sure if or what has changed with this latest update.
Thanks in advance.
I just fixed this same problem by removing a file LICENSE.chromedriver as per this thread: https://github.com/ropensci/RSelenium/issues/264
Use
wdman::selenium(retcommand=T)
to find the file location of binman_chromedriver files.
Navigate to this file location, go to the driver version you're using and delete the LICENSE.chromedriver file. Mine worked immediately after this action, but note that I also tried downgading wdman version to 0.2.5 (I was on 0.2.6) first:
remotes::install_version('wdman',version = '0.2.5')
I'm not sure if it was both actions that fixed it or just the file delete!
Until recently, I was using RSelenium without any problem. When I try to connect to hostr rsDriver() to start a selenium server and browser, I get the following error message:
Could not open firefox browser.
Client error message:
Undefined error in httr call. httr output: Failed to connect to localhost port 5111: Connection refused
Check server log for further details.
Warning message:
In rsDriver(browser = "firefox", port = 5111L, verbose = F) :
Could not determine server status.
I have looked at some answers already proposed, like in this page. However, when I run the command,
> selServ <- wdman::selenium(verbose = FALSE)
> selServ$log()
I get the following error message:
$stderr
[1] "Error: Could not find or load main class c(-Dwebdriver.chrome.driver="C:\\\\Users\\\\user\\\\AppData\\\\Local\\\\binman\\\\binman_chromedriver\\\\win32\\\\109.0.5414.25.chromedriver.exe\","
$stdout
character(0)
I tried to reinstall Java, but without success.
Ok I just solved the issue. The issue was that RSelenium recognises the chromedriver even when using other browsers so when the driver is not compatible to your current chrome version, it would have an issue with rsDriver. In order to solve this, you can either input NULL next to chromever or older chrome driver version from C:\Users\NAME\AppData\Local\binman\binman_chromedriver\win32
rD <- rsDriver(port= sample(7600)[1], browser=c("firefox"), chromever = NULL)
rD <- rsDriver(port= sample(7600)[1], browser=c("firefox"), chromever = 108.0.5359.22)
I am trying to scrape some comments from a job feedback web site using RSelenium.
I am facing a following problem when I try to run this line of code:
library(RSelenium)
rs <- rsDriver(browser = "firefox", check = FALSE)
And then the problem pops up:
[1] "Connecting to remote server"
Could not open firefox browser.
Client error message:
Undefined error in httr call. httr output: Failed to connect to localhost port 4567: Connection refused
Check server log for further details.
Warning:
В rsDriver(browser = "firefox", check = FALSE) :
Could not determine server status.
The latest Java and Mozilla Firefox versions are installed onto my laptop. Also added the path to Java's bin in the Win system options. I have no clue why this problem occurs.
When I try to open the RSelenium I receive this error
[1] "Connecting to remote server"
Error: Summary: UnknownError
Detail: An unknown server-side error occurred while processing the command.
class: org.openqa.selenium.firefox.NotConnectedException
The version of Firefox I have is
Firefox version: 480b10
According to this I tried to update the server version
library("RSelenium")
startServer()
unlink(system.file("bin", package = "RSelenium"), recursive = T)
checkForServer(update = TRUE)
remDr <- remoteDriver()
Sys.sleep(5)
remDr$open()
Sys.sleep(5)
but the problem still exist. Does anyone face this problem? Any possible solution?
From Firefox 48 on-wards the gecko driver/ marionette will be needed to run Firefox with Selenium.
If you have Firefox 48 you can run the gecko driver as follows:
Refer to the guidelines
https://developer.mozilla.org/en-US/docs/Mozilla/QA/Marionette/WebDriver
Download the relevant gecko driver from https://github.com/mozilla/geckodriver/releases
Add it to your PATH or refer to the location when starting binary (see below)
# get beta selenium standalone
RSelenium::checkForServer(beta = TRUE)
# assume gecko driver is not in our path (assume windows and we downloaded to docs folder)
# if the driver is in your PATH the javaargs call is not needed
selServ <- RSelenium::startServer(javaargs = c("-Dwebdriver.gecko.driver=\"C:/Users/john/Documents/geckodriver.exe\""))
remDr <- remoteDriver(extraCapabilities = list(marionette = TRUE))
remDr$open()
....
....
remDr$close()
selServ$stop()
The above currently requires the dev version of RSelenium. Alternatively you can download the Selenium binary from http://selenium-release.storage.googleapis.com/index.html . Pick the 3.0 beta 2 binary to currently run with Firefox 48. Run the binary
java -Dwebdriver.gecko.driver=C:/Users/john/Documents/geckodriver.exe -jar selenium-server-standalone-3.0.0-beta2.jar
