I deployed JupyterHub originally via custom Docker images and kustomzie.
After switching to the z2jh helm chart; we have been having issues with users in Rstudio experiencing 403. While Rstudio does seem to be relatively problematic, I have identified that the port-token cookie is changed whenever this issue occurs.
I cannot find any documentation on what injects this cookie, and had little success searching through the z2jh, jupyterhub, chp, or any loosely related repo I could think of.
What sets this cookie, and more importantly how do I manage when it is reset?
