libwget/http.c in wget2:

        if (nbytes < 0)
                error_printf(_("Failed to read %zd bytes (%d)\n"), nbytes, 
errno);
        if (body_len < resp->content_length) {
                resp->length_inconsistent = true;
                error_printf(_("Just got %zu of %zu bytes\n"), body_len, 
resp->content_length);
        } else if (body_len > resp->content_length) {
                resp->length_inconsistent = true;
                error_printf(_("Body too large: %zu instead of %zu bytes\n"), 
body_len, resp->content_length);
        }

It happens when a server claimed that the response body had XXX bytes, but
then the server only sent yyy bytes.

It is either a bug in the the server, or a network error. There also was a bug
in wget2 when resuming a file retrieval
