Can not connect to the Selenium running in Docker on remote server

[rcepka]

I am struggled for several days, trying to get connected to the Selenium server running on remote docker machine (not my localhost).

I have installed Docker on Ubuntu 20.04. Running firefox -v return Mozilla Firefox 117.0.1.

I did from my server console: docker run -dt -p 4445:4444 selenium/standalone-firefox:117.0 and I see the Selenium nicely running on "http://my-server-ip:4445/ui"

Finally I am trying to connect to Selenium from R. In my Rstudio I run the code:

library(RSelenium)

  remDr <- RSelenium::remoteDriver(
    remoteServerAddr = "my-remote-server-ip",
    port = 4445L,
    browser = "firefox",
    )

  remDr$open()
#> [1] "Connecting to remote server"
#> $id
#> [1] NA

^{Created on 2023-09-16 with reprex v2.0.2}

Computer is just hanging for several minutes and can not connect to the Selenium server. I tried this also with Selenium Chrome server but with no luck. What am I doing wrong please? Many thanks in advance...

RSelenium does not work with the latest version of Selenium (see #280). Either:

1. Use an older version of Selenium (e.g. docker run -d -p 4444:4444 -p 7900:7900 --shm-size="2g" selenium/standalone-firefox:4.8.3). You might have to experiment to find a version that RSelenium is compatible with.
2. Use the newer selenium package, that works with the latest version of Selenium.
