Hi Travis,

We resolved the issue by changing the `host_regex` expression from `ondemand-poc-node-.* `to` ondemand-poc-node-.*?`. Adding the “?” to the end of the regex turned out to be the key.

We got the idea from [this](https://discourse.openondemand.org/t/502-proxy-error-when-opening-file-in-jupyter-notebook/2662) issue by @link89 and the [pull request](https://github.com/OSC/ondemand/pull/2784) therein.

The change did resolve issues with jupyter and RStudio that looked very different from each other.

We believe this might be worth adding to the [documentation](https://osc.github.io/ood-documentation/latest/how-tos/app-development/interactive/setup/enable-reverse-proxy.html#steps-to-enable-in-apache) for other users who encounter the same problem.
