Error 400 on GET or POST method with lightHTTPD server

Question

Hi all, I am facing a strange problem / I am using arduino nano and compact W5100 eternet module I develop a mysql server with PHP script to record the data collected by the Nano For this I use WAMP package on my windows machine, everything goes right with GET or POST method Now I change the server to ANDROID based machine and need to use Lighttpd 1.4.35 server The problem is that with this server nothing works and server answer error 400 bad request I double-check with wireshark application and data are OK I double-check my PHP code on this server (Lighttpd) using external tools and this works with those tools. I conclude that there is something wrong either with the module either with the provided library Any idea to solve this ? Rgds

Francis, make your Android server logging everything which comes from the client. I assume there’s basic log file which would show some details about what is going on, but you would need to log whole header and contents. Error 400 is bad request which means that your Android server does not understand something in the request. One bad character transmitted may cause such behavior of one type of servers while others may just discard bad characters.
