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!
[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 4567 after 0 ms: Connection refused

Warning message:

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.
Update: As of RSelenium 1.7.9 the described problems have disappeared.
I know, similar questions have been asked, but their solutions didn't work for me.
Summary:
I would like to open a Selenium-server and a client under Linux via R's package RSelenium.
But even though I try two ways described in the documentation (while I want to avoid docker)
it doesn't work reliably.
My system:
Linux 5.19, R 4.2.1,
RSelenium 1.7.7, selenium-server-standalone-4.0.0-alpha-2,
chromedriver 104.0.5112.79-2.1, geckodriver 0.31.0 (binman),
I have tested with OpenJDK 11 and OpenJDK 18 (currently)
I. Selenium via JAVA
In the Linux-console
#localhost:~/Documents/selenium> java -jar selenium-server-standalone-4.0.0-alpha-2.jar
20:04:49.470 INFO [GridLauncherV3.parse] - Selenium server version: 4.0.0-alpha-2, revision: f148142cf8

20:04:49.730 INFO [WebDriverServlet.<init>] - Initialising WebDriverServlet
20:04:49.793 INFO [SeleniumServer.boot] - Selenium Server is up and running on port 4444
In R I type:
remDr <- remoteDriver(remoteServerAddr = "localhost", port = 4444L, browserName = "chrome", version = "104.0.5112.79")
and get in the Linux console the output:
20:07:49.463 INFO [ActiveSessionFactory.apply] - Capabilities are: {

The Chrome-Browser opens and the R console gives me the kiss of death:
Error in checkError(res) :
Undefined error in httr call. httr output: Failed initialization
That means, I cannot use the R-console for navigation. The other approach:
II. Selenium via RSelenium::rsDriver
rD <- RSelenium::rsDriver(browser="firefox", port = 4567L, verbose = FALSE)
mostly yields (with a browser window opening)
Could not open firefox browser.
Client error message:
Undefined error in httr call. httr output: Failed initialization
Check server log for further details.
BUT: The very same code can work! Randomly. Or after a long time having R open?!? Endless testing?!?
Suddenly I get several running server/client connections including navigation on web-pages:
$acceptInsecureCerts
[1] FALSE
$browserName
[1] "firefox"
$browserVersion
[1] "103.0.2"
$`moz:accessibilityChecks`
[1] FALSE
$`moz:buildID`
[1] "20220815180539"
$`moz:geckodriverVersion`
[1] "0.31.0"
etc.pp.
But at the latest when I reboot my PC, I get the same error-message again. It also can work after deleting and reinstalling the four drivers via RSelenium in ./local/share. Or when I try the same again, it simply doesn't.
I have never run in such a kind of problem with randomness. Where can it come from?
PS: The server log, if it doesn't work, can have additional lines, which I add:
> rD$server$log()
$stderr
[26] "Missing chrome or resource URL: resource://gre/modules/UpdateListener.jsm"
[27] "Missing chrome or resource URL: resource://gre/modules/UpdateListener.sys.mjs"

Maybe you can try the following approach which relies on Docker :
library(RSelenium)
url <- "https://www.hubs.com/3d-printing/#/?place=New%20York&latitude=40.7144&longitude=-74.006&distanceLimit=250&distanceUnit=miles&shipsToCountry=US&shipsToState=NY"
shell('docker run -d -p 4445:4444 selenium/standalone-firefox')
remDr <- remoteDriver(remoteServerAddr = "localhost", port = 4445L, browserName = "firefox")
remDr$open()
remDr$navigate(url)
remDr$getPageSource()[[1]]
Flutter/Dart
Why does http.get('http://18.191.190.195/') throw above error while using chrome browser http://18.191.190.195/ shows the Test Page and says:
If you can read this page, it means that the Apache HTTP server installed at this site is working properly.
Cause: Poor network connection.
Suggestion: Error reporting should be more descriptive from Dart.
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!
I have RSelenium (the package) installed, to do some scraping of NHL statistics from hockeyreference.com
It was working, all fine, but recently stopped working, giving this error:

I've tried reinstalling, but could not get it working. My original install is outlined in this question (using homebrew, with the latest chromedriver installed):
Css selector issue with rvest and NHL statistics
Any help would be great. The code I'm running with RSelenium is here:
https://github.com/papelr/nhldatar/blob/master/nhldatar/R/nhldatar-phase-2.R
TL;DR, I can't get the rsDriver argument to work, and it gives the error posted above:
rsDriver(port = 4567L, geckover = NULL, phantomver = NULL)
remDr <- remoteDriver(browserName = "chrome")
remDr$open()
If RSelenium works (opening a chrome browser), then the rest of this will run! Thanks!
I reccomend to:
install docker for Mac,
pull the image for chrome, firefox (recommend version 3.5.1) or phantom
run image in docker: docker run...
create remotedriver:
remDr <- remoteDriver(remoteServerAddr = "here you IP", port = 4445L,
browserName = "firefox")
if you have debug version you can watch in VNC what are you doing
