There was no meaningful change to the PP code in that period, but I updated the dependencies to the JSoup library which is used to extract data from HTML.
Apparently JSoup became more picky on the HTML.
I noticed that your service returns all rows as thead (header rows).
If you change it in such a way that you add the body inside a tbody, it should work.
Or you remove the thead and just use tr tags, then it works also.
