System details
RStudio Edition : <-- Server -->
RStudio Version : RStudio 2022.07.2+576 "Spotted Wakerobin" Release (e7373ef832b49b2a9b88162cfe7eac5f22c40b34, 2022-09-06) for Ubuntu Bionic； Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:129.0) Gecko/20100101 Firefox/129.0
OS Version : Ubuntu 20.04.6 LTS ；Release: 20.04
R Version : 4.1.3
Steps to reproduce the problem
when I run code chunk in Rnotebook, the browser prompted a message “nable to establish connection to rstudio server”
Describe the problem in detail
the problem seemed to be related to the zerotier-one service.
Initially, I rebooted my server, which is assumably only accessible via local network ip address and found that the network didn’t work anymore: the ssh remote and the Internet connection were all lost. I found that the network configuration was lost after the reboot. Therefore, I reconfigured it via ‘systemd networked’ service, and everything seemed ok then.
However, when I accessed the Rstudio server via “https://the physical local network ip:8787” , and tried to run code in Rnotebook, the problem above occurred. I tried uninstall Rstudio & R, and reinstall them again, but neither helped.
Later, I found two methods could avoid this problem:
- Creating an ssh tunnel via
ssh -L 8787:localhost:8787 username@local network ip, and then access the Rstudio in a browser via “localhost:8787”. - Access the Rstudio through a network created by zerotier-one, from a network independent of the physical local network where the server was in. In a similar way, accessing via “https:// zerotier-one-ip:8787” in the browser could avoid this problem, too
Overall, it seems that there may be some settings created by zerotier-one, which led to the loss of network configuration after rebooting and the network error when access via physical ip:8787 is applied.
But I have no idea how to solve this problem and restore to the previous normal state. Can you please help me work out on that?
Thanks very much !
p.s. for any potential information, the jupyterhub service on my server encountered a similar problem: it is okay to create new files, rename files, and run code in notebooks. However, the network error occurred when I tried to save any change made to the notebook. Also, the above two methods could avoid that.
