RStudio "Cannot connect to R" - tried several versions

RStudio IDE
1

I'm not an R expert by any means, but I am required to support our end users and we're seeing an intermittent issue:

Cannot Connect to R
RStudio can't establish a connection to R.

I've installed R (4.3.2 (64-bit), but also happens with R 4.3.1) and then R Studio Desktop 2023.12.1+402 (and 2023.06.2+561), in that order.

I've blown away the RStudio directories from both appdata\local and appdata\Roaming and the issue persists. Usually a restart of the machine will fix it.

Any ideas? We also have VMware Horizon Client installed.

I do note that hosts has this:

127.0.0.1 view-localhost # view localhost server

I removed this from a machine, flushed DNS and retried, but it still fails.

Hi @glenn.turner thank you for providing the diagnostic report.

I can see this error towards the end of the report:

2024-02-09T06:18:21.372143Z [rsession-USERID] ERROR Unable to retrieve user home path. ...

Further up, I can see your Environment variables show:

HOME : \PATHTHATDOESEXIST\USERID
HOMEDRIVE : H:
HOMEPATH :
HOMESHARE : \PATHTHATDOESEXIST\USERID

I am presuming that those values are replacements you have entered, but the H: suggests drives that are not local. Do you get a better result by setting the HOME environment variable to a local drive (eg: C:/User/${USERNAME})?

Thanks for the reply @Lachlan_Simpson . They are not local because we need to back up user data (we don't use roaming user profiles). Without changing those, is there anything we can do in terms of R- or RStudio-specific variables, preferably with those also referencing a variable so we can do it at install time per-machine, for example:

R_USER = ${USERPROFILE}\RStudioData

Hi @glenn.turner are you able to temporarily change the values to local values to test if it works please? Even if it isn't the desired solution, it will help us by providing more diagnostic information. Thanks

Hi, @Lachlan_Simpson one of our most experienced R users has changed HOME to a local drive and it's still an issue. His machine is currently unable to launch R Studio and connect to R.

rdesktop.log shows:

2024-03-20T04:25:22.451Z ERROR Failed to load http://127.0.0.1:8111: Error: ERR_CONNECTION_TIMED_OUT (-118) loading 'http://127.0.0.1:8111/'

Nothing new in rsession-userid.log**

Asking the user to run "C:\Program Files\RStudio\rstudio.exe" --run-diagnostics from a CMD.

Looks like the doco here Running a Diagnostic Report – Posit Support is out of date, as the .lnk is not in the expected location.

Hi @glenn.turner,

Thank you for your patience while we looked into this further, and for the feedback about our documentation. I will ask the team to review it and correct as necessary.

First, I can confirm that you have helped us find a bug, but unfortunately it's solution will only improve the error messages we see, rather than solve the issue you are experiencing.

Specifically, the error message "Unable to retrieve user home path. HRESULT:..." was unfortunately incorrect / misleading. You can see that an improvement has been merged already: implement fallback when computing user session directory by kevinushey · Pull Request #14464 · rstudio/rstudio · GitHub

To address the issue you have - the fact that the issue is apparently intermittent, and you are using network shares, makes us thing that the issue is related to timeouts during R session initialization.

Unfortunately the best solution we have in the short term is that you set a local directory for the user's home, as we can't control the starting of R sessions.

The R documentation does have a comprehensive explanation of the HOME and working directories, and how to set environment variables: R for Windows FAQ

It may be that the solution is a wrapper script that sets a local directory initially, but then an .Rprofile or .Renviron file resets the HOME after the session has initialized?

Thank you. You're right - the issue is with timeouts. Interesting to know that it might be R-related and nothing to do with R Studio itself. I'll try to test R natively without RStudio the next time I get a timeout.
