We are running the latest version of posit workbench on a test machine (2022.12.0+353.pro20) and are running into an issue with launching jupyter lab or notebook sessions. The basic configuration is working correctly and we are able to successfully launch RStudio and VS Code sessions but both Jupyter sessions result in a successful launch but opening the session gives the following error:
certificate verify failed (SSL routines, tls_process_server_certificate)
Looking at the launcher diagnostics it is clear that the jupyter sessions are being launched with an https whereas with pervious versions of workbench these were http addresses. jupyter.conf, rserver.conf and launcher.conf are all more or less completely standard using defaults - I'm happy to post them if they would be helpful in diagnosing the issue.
Example launcher diagnostics:
