Do you have HTTP enabled for all of the HDMI inputs in the "Stream" tab in the LinkPi web interface? If only HLS works that might be the only enabled protocol.
If you could share a screenshot of the "Play URL" on this screen it might help us further troubleshoot your issue.
Yea I had this enabled, the factory reset seems to have fixed the issue for me
Hi everyone! As I am not currently on my home network, I am not able to use the local network ip address to access my LinkPi GUI. Is there a way to access the LinkPi remotely?
I was wondering about that. I have been using Tailscale for most of my devices for years. I never was sure about how to use it for devices which don't accept a client software installation. I'll try setting up a subnet on my Tailscale server, which happens to be the Synology NAS which hosts my DVR.
Up to now, the only way I have been able to get to the LinkPi when I am a way from home is to remote into my desktop PC and connect to the LinkPi from there. Tailscale will be a more direct way to connect.
Thanks for the tip!
Well, it was a good idea. However, I now remember why I hadn't set up a subnet before. I simply don't have the savvy to pull it off. I don't think that I ever set up a Tailscale server as it seemed too complicated for me.
Thanks. I'll give this a try a little later this afternoon. Right now, I have to head outside to clean out a rodent nest the chipmunks have been building behind the BBQ. Darned little critters need to relocate. 
Dont understand your logic here at all. When using an exit node you should route your actual network subnet. Doing a /23 as opposed to a /24 doesnt solve anything. Lets say you have 192.168.0.0/24, if you made that a /23 all that does is route 192.168.0.1-192.168.1.254 through tailscale. Since your LAN is 192.168.0.0/24, the second half of the /23 is never used. While techincially not hurting anything, it is unnecessary. To avoid going through the tailnet on your local lan just disconnect tailscale.
The linkpi website mentions the power supply for ENC5 as 5A. Is that an accurate description?
The website doesnt mention the voltage but i am guessing it is 12V5A i.e. 60W. What kind of PoE device can provide 60W?
That is likely a typo. The typical power for an ENC1 is 12V, 1A or 2A. You can also run 5V (typical USB charger) at 2A.
EDIT: Apologies, I misread you wrote ENC5. You are correct. The original ENC5 calls for 12V5A. If you are considering a new encoder to purchase, select the ENC5 v2, which is much better and is 12V2A.
Yeah. In spite of my hesitance to throw money at equipment, I did jump right into an ENC5. My LinkPi setup includes three onn 4k boxes and three Roku 4k sticks. I will say that, so far, I mostly rely on TVE and several docker containers for the bulk of my viewing and recording. I rarely have more than 1 or 2 tuners running at a time. I consider my LinkPi setup as "futureproofing" because I see access by my preferred methods eroding away. Already, there are a few channels which can only be accessed directly though my provider's apps.
I'm probably headed that direction, too. TVE authentication with DTV is temperamental. When I had YTTV, TVE was extremely reliable. In contrast, DTV TVE channels fail on me every so often.
What place has the best price for ENC5 (US customer)?
Check ebay
Amazon usually is cheaper for LinkPi stuff. All the eBay shipments from China lately have relatively high shipping cost. Import costs maybe?
I had some thermal issues last summer. As you have found, separating your devices makes a difference.
Creating some air flow may help as well. If you have a spare USB port on one of your devices, perhaps you could plug in a small USB powered fan to blow across your setup.
The laptop cooling pad is a really good idea. 
Same here. I bought about 2-3 cooling pads and just put everything on top of them. It can get hot as crazy here in Miami but I moved in an apartment with central AC so it doesn't affect the devices as it did in the old place
That's a lot of Osprey boxes! This makes me think about @jsfullam's use of Taco Trays. Maybe get one of these letter sorters for desks and stack Osprey boxes vertically and get better air flow from below. Double check spacing size for Osprey fit, of course.

Switch them Osprey's to POE with 1’ HDMI cables and you’ll be looking clean!!
