 * Hi lorenademariano,
 * The 503 error indicates a connectivity issue with the Tinify API. The is normally
   a temporary error and should be resolved quickly.
 * Could you perhaps try compressing some more images, and if the problem persists,
   please send us an email to [support@tinypng.com](https://wordpress.org/support/topic/error-while-parsing-response-syntax-error-4-http-503-parseerror/support@tinypng.com?output_format=md)
   and we will assist you further.
