@kylepyke I'm not sure if you still read this thread, since there was no feedback from you. So then nobody could help you and I would "close" the thread in maybe two weeks. This would be sad, especially since monkeybrain was able to answer you.
@monkeybrain Welcome to the forum, thanks for your help.
@Mathilde "Pangolin" seems to be this app here: https://github.com/fosrl/pangolin/blob/main/README.md . Almost as popular as CryptPad it seems, 5.9k stars. A bit shorter / easier is the original announcement on Reddit: https://www.reddit.com/r/selfhosted/comments/1hujxxo/pangolin_beta_your_own_tunneled_reverse_proxy/
