Cannot comminicate with MATLAB when using public IP in Jupyter

When using an externally accessible IP when starting Jupyter, e.g. jupyter lab --ip xx.xx.xx.xx, I get the error

ERROR:MATLABKernel.fd50cfab-30d9-4841-b2d2-6e95b3e0a10c:Found a startup error: 
                Error: MATLAB Kernel could not communicate with MATLAB.
                Reason: Possibly due to invalid jupyter security tokens.

upon executing any Matlab command in a Matlab notebook.

When using the default localhost everything works fine.

The use case is to access Matlab on a remote server via the web browser. While this works fine with localhost and suitable ssh tunnels, using a "outwards" facing IP for the jupyter process would make things easier. Is this behavior supported?
