Report of Stops keeps loading

When i try to check the stops on the reports, it keeps loading and then I got an error communication failure.
Every other report, like trip summary works

What version of Traccar are you using?

i think 4.5 it's on the legacy interface

I recommend upgrading. There are some significant performance improvements to trips and stops reports.

Yeah it's our plan to update, but the stops report was working fine until couple days.
