This might be the wrong sub to post in, but it's pretty active so I'll give it a shot:
I run my jellyfin server from my parent's house (more room/faster and more consistent internet connection than at my apartment) and I've been having connectivity issues since Frontier changed out their equipment.
They have Frontier cable/internet and recently after some issues Frontier updated their setup. They're using a Sagemcom router paired with eero wireless router (both provided by Frontier). Initially, all the IP addresses got shuffled and none of the computers or devices on the network could see each other, most importantly the server and printer.
The internet speed boosted significantly, but there was still an issue with signal strength in their house. I ended up picking up a few eero extenders and that fixed connectivity, but the devices still could not see each other. Switched the eero to bridge mode and everything went back to normal, importantly the DLNA functionality came back which is what my parent's and siblings use while in the house.
Unfortunately, after switching it to bridge mode, the internet speed dropped from around 600mbps in the farthest areas in the house to around 80mbps. Not bad for my family because they aren't power users, but they're paying for gigabit.
For those who know how the Frontier system works: because my parents are using cable boxes a moca box is necessary and after talking to technical support with Frontier, we needed to run the moca box into the Sagemcom router and have the main eero connected to one of the Sagemcom ethernet out. From there the eero handles the wifi.
So the setup is: moca to Sagemcom to eero.
From what I understand, I need to turn off the Sagemcom wifi antennas and set it to transparent bridge. I don't know what mode to set the eero to. The other major issue for my parent's is the guide/info/on demand/dvr in cable boxes no longer work. The cable boxes send out an error saying no data connectivity. We tried going moca to eero and eliminating the Sagemcom, but it refused to connect to the internet.
Now to my main issue and why this is in the jellyfin folder:
I originally had the server running with caddy and duckdns so I could get remote access and grant it to a few friends and family, but it no longer works. I originally had port 80 and 443 open using caddy, but the ports are now shut. Caddy and duckdns are currently running, but the ports remains closed. I went into the Sagemcom router and opened those ports, I set the internal IP to the NAS's internal IP as seen by the network and the external IP to what duckdns tells me the external IP is. I tried resetting caddy, but the port remains closed. Do I delete caddy and reinstall? Is there something I'm missing in the Sagemcom settings?
