I am using the following configuration and it seems to work.
Truenas also uses a websocket API that I am unable to test at the moment the endpoint is /websocket
I haven't included it as I am not able to verifiy it works. The docs are here: https://www.truenas.com/docs/scale/24.10/api/

## Version 2025/07/15
# make sure that your dns has a cname set for truenas
# check your truenas settings for the http listening port of the web ui (default is 80)
# remember to add your proxy IP to the Allowed IP Addresses table in the "Advanced settings" section of truenas
