I am using the following version of Windows 10: Build 20190.rs_prerelease.200807-1609

Found some similar post few years back, but none of them have solution I can use.

RStudio launches to "This site can’t be reached".

Dear all, I downloaded R (3.6.0) and RStudio for Windows 7 SP1, 64bit. R works fine, but if I try to start RStudio I get the following screen: [RStudio-fail]. RStudio tells me: "This site can't be reached. 127.0.0.1 refused to connect." Also none of the menu bars are cllickable. I tried to reinstall R and RStudio without an antimalware-program and without an activated firewall, but this did not solve the problem. Following a search in the web I checked if "localhost" and "127.0.0.1" are on the list of approved Hosts and Domains; in Firefox, this is the case. There was a slightly similar post a year ago, but the Problem was not the same, as it was on Windows 10 and as RStudio was usabl…

Bizarre Behaviour: RStudio launches to "This site can’t be reached" page when opening scripts

Hi everyone, I am running R (3.5.0) and RStudio (1.2.622) on Windows 10 (10.0.17134 Build 17134) and have come across a weird issue that I'm hoping someone can help me figure out. If I launch RStudio from my Start Menu or a regular shortcut, everything is fine and RStudio launches without issue. However, if I launch RStudio by opening a .R or a .Rmd file from somewhere on my harddrive, Rstudio looks like this when it launches: [Rstudio] (A "This site can't be reached: 127.0.0.1 refused to connect" error message). None of the menu bars are clickable. Anyone have any idea what is causing this or how I can fix it? I don't have any custom .Rprofile or anything running at start-up (even the…

I am having a similar problem with this Insider build of windows. The regular Rgui and Rterm.exe won't even run, so I think it's a problem with R. I've tried several version of 3.6.x and 4.0.x. I'm hoping it gets fixed this week in the new Windows prerelease build, but have no inside information.

[mxfeinberg]

I am having the exact same issue on this build. My logs have some more information though.

I am running Windows 10 Pro Build 20190 and the 32-bit version (not the 64-bit one) of R patched (as of 8/18/2020). I was having the same problem as "dapidc" and tried 3.6.3, 4.0.0, 4.0.1, 4.0.2, and some of the patched versions. The problem is likely with the 64-bit version of R; it turns out the 32-bit version does work: the terminal version, the GUI version, and under RStudio.

I'm not sure how to get this information to the R team and not sure they would even care because the is a Dev build of Windows.

[dapidc]

I've downloaded latest RStudio, and now it gives clearer messages. However, still no guidance on at least what should be done, other than check the R.

This is on Windows 10 build 20190, 200807-1609.

[dapidc]

If I go back to previous build, there is no problem running Rstudio:

This was a bug in Windows Dev Preview Built 20190 (released 8/12/2020). The bug has been fixed in Built 20201 (released 8/26/2020).

I had the same error when using Rstudio with MacOs Catalina. I had to downgrade (until Version 1.1.463) because last and current version (1.3.1073) did not work.
