I'm trying to scrape the content from http://google.com.
the error message come out.
library(rvest)
html("http://google.com")
Error in open.connection(x, "rb") :
Timeout was reached In addition:
Warning message: 'html' is deprecated.
Use 'read_html' instead.
See help("Deprecated")
since I'm using company network ,this maybe caused by firewall or proxy. I try to use set_config ,but not working .
I encountered the same Error in open.connection(x, “rb”) : Timeout was reached issue when working behind a proxy in the office network.
Here's what worked for me,
library(rvest)
url = "http://google.com"
download.file(url, destfile = "scrapedpage.html", quiet=TRUE)
content <- read_html("scrapedpage.html")

This is probably an issue with your call to read_html (or html in your case) not properly identifying itself to server it's trying to retrieve content from, which is the default behaviour. Using curl, add a user agent to the handle argument of read_html to have your scraper identify itself.
library(rvest)
library(curl)
read_html(curl('http://google.com', handle = curl::new_handle("useragent" = "Mozilla/5.0")))
I ran into this issue because my VPN was switched on. Immediately after turning it off, I re-tried, and it resolved the issue.
I was facing a similar problem and a small hack solved it.
There were 2 characters in the hyperlink who were creating the problem for me.
Hence I replaced "è" with "e" & "é" with "e" and it worked.
But just ensure that the hyperlink still remains valid.
I got the error message when my laptop was wifi connected to my router, but my ISP was having some sort of an outage:
read_html(brand_url)
Error in open.connection(x, "rb") :
Timeout was reached: [somewebsite.com.au] Operation timed out after 10024 milliseconds with 0 out of 0 bytes received
In the above case, my wifi was still connected to the modem, but pages wouldn't load via rvest (nor in a browser). It was temporary and lasted ~2 minutes.
May also be worth noting that a different error message is received when wifi is turned off entirely:
brand_page <- read_html(brand_url)
Error in open.connection(x, "rb") :
Could not resolve host: somewebsite.com.au

I have a problem with obtaining data from specific website - when trying to download raw website data with R 3.6.3 using following example code:
website_raw <- readLines("https://tge.pl/gaz-rdn?dateShow=09-02-2022")
The result I got is:
Error in file(con, "r") : cannot open the connection In addition: Warning message: In file(con, "r") : InternetOpenUrl failed: 'the connection with the server was reset'
readLines() method used to work fine on this website but from one week on it fails. I've tried also download.file() method: at the beginning the result was the same (error, connection reset) but after setting options(download.file.method = "libcurl"), website file starts to download but then it suddenly stops with information:
trying URL 'https://tge.pl/gaz-rdn?dateShow=09-02-2022'
Error in download.file("https://tge.pl/gaz-rdn?dateShow=09-02-2022", "test.html") :
cannot open URL 'https://tge.pl/gaz-rdn?dateShow=09-02-2022'
In addition: Warning message:
In download.file("https://tge.pl/gaz-rdn?dateShow=09-02-2022", "test.html") :
URL 'https://tge.pl/gaz-rdn?dateShow=09-02-2022': status was 'Failure when receiving data from the peer'
I've tried also disabling Use Internet Explorer library/proxy for HTTP in Rstudio Global Options but it didn't help. Another solution that I've tested was read_html() from rvest package - getting following error:
Error in open.connection(x, "rb") : Send failure: Connection was reset
Downloading data from other websites works fine though, with all considered methods.
Is there any way I can download data from this website with R?
Any kind of help or suggestion will be highly appreciated
In order to find some features that I need, I want to establish a connection to a website using open(mycon, "r"). To do this, I used the code below which is provided by #Dunois:
myx <- httr::HEAD(example)$url
mycon <- url(myx)
open(mycon, "r")
where example is a link to a website. This code works perfectly for all websites; however, in some unique cases like "https://www.pixilink.com/140079#mode=tour" or "https://www.pixilink.com/141152#mode=0" it doesn't work. These websites exist and I check them in my browser and I am not sure why the connection cannot be established. The error message I get is:
Error in open.connection(mycon, "r") : cannot open the connection In addition: Warning message: In open.connection(mycon, "r") : cannot open URL 'https://www.pixilink.com/140079#mode=tour': HTTP status was '400 Bad Request'
I appreciate it if you can shed light on this and clarify why I get this error message?
When I do some webscraping (using a for loop to scrap multiple pages), sometimes, after scraping the 35th out of 40 pages, I have the following error:
“Error in open.connection(x, "rb") : Timeout was reached”
And sometimes I receive in addition this message:
“In addition: Warning message: closing unused connection 3”
Below a list of things I would like to clarify:
1) I have read it might need to define explicitly the user agent. I have tried that with:
read_html(curl('www.link.com', handle = curl::new_handle("useragent" = "Mozilla/5.0")))
but it did not change anything.
2) I noticed that when I turn on a VPN, and change location, sometimes my scraping works without any error. I would like to understand why?
3) I have also read it might depend of the proxy. How would like to understand how and why?
4) In addition to the error I have, I would like to understand this warning, has it might be a clue that leads to understand the error:
Warning message: closing unused connection 3
Does that mean that when I am doing webscraping I should somehow at the end call a function to close a connection?
I have already read the following posts on stackoverflow but there is no clear resolution:
Iterating rvest scrape function gives: "Error in open.connection(x, "rb") : Timeout was reached"
rvest Error in open.connection(x, "rb") : Timeout was reached
Error in open.connection(x, "rb") : Couldn't connect to server
Did you try this?
https://stackoverflow.com/a/38463559
library(rvest)
url = "http://google.com"
download.file(url, destfile = "scrapedpage.html", quiet=TRUE)
content <- read_html("scrapedpage.html")
I was trying to web scrape some reviews using R rvest package and actually succeded until I interrupted my session with the red stop button (going into details).
Then I started to get this error:
Error in open.connection(x, "rb") : HTTP error 503
when using the function read_html
I'm pretty sure it's due to the interution but I have no idea what exactly happened! Please help, I didn't find any solution on the web.
If it can help, here's a piece of code that has been interrupted:
reviews_links <- rbindlist(apply(med_links, 1, function(url) {
url2 = read_html(paste('https://otzovik.com', url, sep = ""))
data.frame(url2 %>% html_nodes("h3 a") %>% html_attr("href"), stringsAsFactors = FALSE)}),
fill = TRUE)
I also tried to restart either R and my computer - didn't help
UPDATED
Apparently, it was just the site blocking my requests. Solved this problem by using delays and changing user-agent from time to time.
I am trying to download financial data of companies. I have used getFin() quite a lot without encountering any problem.
Right now, I am unable to download any data and when I use e.g. this code (and basically any other valid symbol instead of "AAPL"):
getFin("AAPL")
I get the following error message:
Error in download.file(paste(google.fin, Symbol, sep = ""), quiet = TRUE, :
cannot open URL 'http://finance.google.com/finance?fstype=ii&q=AAPL'
In addition: Warning message:
In download.file(paste(google.fin, Symbol, sep = ""), quiet = TRUE, :
cannot open URL 'http://finance.google.com/finance?fstype=ii&q=AAPL': HTTP status was '403 Forbidden'
However, if I try to access the website http://finance.google.com/finance?fstype=ii&q=AAPL via a browser, I have no problem with accessing the website.
So why am I unable to download data with getFin() in RStudio all of the sudden?
Have you tried clearing your cache or going incognito and accessing the URL?
Assuming you are on a linux server and using PHP you could try updating your PHP version it should be on the Google finance api documentation
