I really enjoy reading in my hammock. Usually I set it up in my backyard but it’s also easy to take to a park or on a hike. I just use one of those camping ones that packs away to the size of a nalgene water bottle.

Sidenote, I also use one of these security straps on my e-reader. It allows me to read laying down in the hammock or in bed without having to completely hold onto my reader. Definitely recommend.

Aptera is doing this with custom solar cells and they claim it’ll provide up to 40 miles of range per day. https://aptera.us/

Can you ping the server from your phone successfully? You can use an app like this to check: https://play.google.com/store/apps/details?id=net.he.networktools

Making sure you have layer 3 connectivity first would be a good first step. If you don’t, I would start by troubleshooting at layer 2. Run a packet capture on both your phone and server while trying to connect to determine where the disconnect is. Make sure ARP is resolving properly.

If layer 3 IS working, move up to layer 4 and make sure you are using the correct port, http vs https, etc
