I succesfully connect to notebooks thanks to our Jupyterhub. Don’t know if my VPN is not stable enough however it is strange because I do not have problems on youtube for example.

A quick update on this issue. We have a new environment discovery module, we are working on getting it to parity with the types of environments that we support. A change we did was to avoid running python and get as much detail about an environment using meta-data only. In cases where we do need to run python we throttle the number of processes to reduce the load. We are working on some bugs with the new code, when it is ready I will report back here with instructions on how to enable it.
Please try opting into
pythondiscoverymoduleexperiment. This should resolve most of the issues where the extension ran too many python processes on startup. This will soon be enabled for all users, so closing this. Anyone running into this issue please try this and if you run into any bugs please file separate issues.
