Mousam fails to display forecast

I'm using the snap version on Ubuntu 26.04 LTS.

The window shows only error message: Fetch Error Expecting value: line 1 column 1 (char 0).

I've enabled the debug mode and this is the mousam.log after a couple runs of the program.

And here is what I get in terminal:
