I have 404 page only for one page; the others are ok!?

Hi Guys,
Like in the Topic Title I have the page 404 only in case I want to go to next page from this:
https://www.automotivespace.it/sviluppo-rete-2/
In fact this is the page 2
https://www.automotivespace.it/sviluppo-rete-2/page/2/

In all the others page I haven’t this problem.

Could you help me to find solution?

Many Thanks
