The box was in an exposed location, and has duly suffered.
Adaptable boxes, as above, are designed for indoor applications. Boxes with seals are available, but as can be seen, are not very effective.

For outdoor work, junction boxes of minimum IP55 rating will give effective results, with 'CW' outdoor armoured glands.
