Remote machine not showing upon firewall installation

[remix4376]

I recently installed an OPNsense hardware firewall and had to reconfigure my home network as a result, since the firewall acts as the DNS & DHCP services for the network. However, I have a headless Debian 13 server that no longer appears in the web client. The Folding@home installation on the server is inside of a Docker container and the compose file was not changed during the firewall installation. The account token in the compose file is still the same as the token that displays in the web client. The domain foldingathome.org is pingable from the Debian server. The Docker image I use is lscr.io/linuxserver/foldingathome:latest

Attempting to access port 7396 through the web browser using the Debian server's IP address redirects me to the same web client, so I am unsure how to reconnect the machine. I have tried deleting and remaking the Docker container. Attempting to pull the Docker image says that the image is up-to-date. Any help is appreciated.

If you have the client linked via account-token, you don't need to directly access the instance in the docker image.
Just use (logged in)
https://v8-5.foldingathome.org/

The client redirects because there is no local web control being served by the client.

Make sure all system clocks are correct. The client connection to the api and node servers will fail if the time is off.

The system time seems fine. I can SSH into the Debian server and the date command gives me the same time as my desktop.
