If you are using a our R studio app from the application catalogue, here are some troubleshooting tips based on errors we have seen in the past.  Of course, if these do not help, you can always contact the help desk. 


Error #1:

"Could not connect to the R session on Rstudio Server.

Error occurred during transmission (6)"


Possible Solutions:

First try reboot your instance. 


If this doesn't work, try the instructions here to reset a user state on an R Studio instance.


If you can't find the "." folders/directory mentioned in the support articles, it might all be in a folder/directory called ".rstudio" (use the command "ls -al" to see what's there, while connected to your instance via SSH) which you can rename to ".rstudio-backup" by running "mv .rstudio .rstudio-backup".


Error #2:

The previous R session terminated abnormally; LOGGED FROM: rstudio::core::Error {anonymous}::rInit(const rstudio::r::session::RInitInfo&) src/cpp/session/SessionMain.cpp:698


Possible Solution:

The database may be corrupt. Try delete the /home/<user>/.local/share/rstudio folder. This should allow Rstudio to load again. 


Error #3

If your Rstudio app or Remote Desktop log in times out or leaves a blank screen.


Possible Solution:

Your volume connected to the R studio app could be full. You will need to connect to your instance via SSH or connect to your instance via Filezilla, and remove some files to increase diskspace. Alternatively you can also expand the size of your volume, if you have quota. View the tutorial here.
