Hi,
Hi, I don't know anything about LuaSocket, but I did notice the first line of your script is #!/usr/loca/bin/lua perhaps it should be #!/usr/local/bin/lua or this might just be a typo in your post, or maybe you really do have a "/usr/loca" directory...
LW and I tried to replicate the problem and it looks like whatever was causing it was on the server side and isn't there anymore. So nothing to worry about. Kind regards, Diego
