A JSONArray text must start with '[' Error

in my tests, the page returns an empty array. ( if (lines.length<=0))

This you have to skip (with continue command).

(maybe they return empty lines when too much inquiries from the same IP occur??)

No use to test for the first char in this case.

TRIM

But I used trim() on the String before parsing it which seemed to help

    lines[0] = trim(lines[0]);
    JSONObject link = parseJSONObject(lines[0]);

Result

here is one result:

(but the results were different every time)
(one star is one empty line)

 0 2  { Cannonball
 1 6  { Cannon base
 2 8  { Cannon stand
 3 10  { Cannon barrels
