@Juraj Your solution worked for me, if you post an answer I will accept it. As background, I tried the Ethernet lib vs. Ethernet2, I tried HTTP/1.0 vs HTTP/1.1, also adding just a client.flush() statement after my requests. I tried using just an IP address to avoid the DNS requests and speeding things up by using a different, faster, DNS like 1.1.1.1 or 8.8.8.8. Finally the two things that helped were, keeping the connection open whenever possible with Connection: Keep-Alive and the StreamLib library ChunkedPrint example.

The only things I can think of to try HTTP/1.0 instead of HTTP/1.1. Or maybe combining all the client.prints so everything is send in a single packet, instead of possibly multiple (I couldn't figure out if that is even the case).

| Aug 6, 2019 at 23:47 | comment | added | jmb2341 | @jsotola yes, I am able to connect to either server using a raspberry pi on the same network as the arduino in Uganda (connected to the same router). I am also able to connect to both servers with both attempted Arduino sketches from the US. I am here considering a raspberry pi as a computer. | |
