This is a strange one. My home wifi works fine on my Droid 4 for most sites. But when I go to my profile page on Amazon, I then select the link: "See all 19 reviews", and I get a long timeout with the error: "Server failed to communicate. Try again later." Needless to say, this works fine on other devices connected to my network, as well as when I use 4G. I will try my phone on other wifi networks to see if I get a different result. I followed-up with Verizon, and they can't reproduce the problem on their Razor. Android 2.3.6, of course. After searching for posts, I found one mention of this error message in 2010, but no resolution. Someone thought it might be due to a server certificate issue. I am using a D-Link DIR-827 router, and have tried every wireless mode (can't see how this is a wireless issue), as well as trying hard-coding a static IP and primary/secondary DNS server addresses in my phone (those were the same ones my ISP uses). Thanks for any light you can shed on this problem.
