We have an instance of R studio running on port 8787 under Ubuntu 16.04.5 LTS. We can access it normally from work using:
server_url:8787
When not at work, after connecting to work VPN, we normally set an ssh forward using:
ssh -N -f -L localhost:8787:localhost:8787 username@server_url
And then, access R studio through a browser using the address:
localhost:8787
Recently, we have been unable to access R studio from outside work (from work, it is still fine)
Forwards to other ports continue to work normally, but forwards to port 8787 don't seem to work anymore.
Any reason what could be causing this and/or how can I properly diagnose? Any help will be highly appreciated.
