extract_tables function status was 'SSL connect error' error

[muhammetozkaraca]

During the last two days, I am trying to install tabulizer package so that I can retrieve some information from an online pdf and conduct some analysis on this data. I managed to upload the package in my R Studio, however when I run this line of code

library(tabulizer)  
library(tabulizerjars)
library(dplyr)

url <- "http://www.sbb.gov.tr/wp-content/uploads/2020/04/KonutPolitikalariOzelIhtisasKomisyonuRaporu.pdf"
out <- extract_tables(url)

I get the following error

Error in utils::download.file(path, tmp, quiet = quiet, mode = "wb") : 
  URL 'http://www.sbb.gov.tr/wp-content/uploads/2020/04/KonutPolitikalariOzelIhtisasKomisyonuRaporu.pdf' açılamıyor
Ek olarak: Warning message:
In utils::download.file(path, tmp, quiet = quiet, mode = "wb") :
  URL 'https://sbb.gov.tr/wp-content/uploads/2020/04/KonutPolitikalariOzelIhtisasKomisyonuRaporu.pdf': status was 'SSL connect error'

To solve this problem, I have tried a couple of solutions. Based on this solution at the Stack, I deleted "s" from http but the error still says "https" which I could not understand.

To check whether this situation is unique to this website, I also tried a similar attempt in another website by the following code;

url <- "http://en.wikipedia.org/wiki/HTTPS"
out <- extract_tables(url)

At this time, I received this error;

Error in .jcall("RJavaTools", "Ljava/lang/Object;", "invokeMethod", cl,  : 
  java.io.IOException: Error: Header doesn't contain versioninfo

When I looked at some solutions, I saw this this one. The solutions at this link mostly were about the previous versions of Java as far as I understood. However, I recently dowloaded Java on my Mac and its version is

java version "1.8.0_311"

Based on the solution in this link, I also run the following code

.jinit()
.jcall("java/lang/System", "S", "getProperty", "java.runtime.version")

which game me this result

"1.8.0_311-b11"

Therefore, I do not think my problem is occurring due to previous versions of Java. I also attached my session Information. If you help me on this issue I will be really glad for that. Thank you in advance.
