but I could fix it by adding one line before esp wifi start:

...
ESP_ERROR_CHECK(esp_wifi_config_11b_rate(WIFI_IF_STA, true));
ESP_ERROR_CHECK(esp_wifi_start());
...

my theorie is:
APs do not support old 11B protocol anymore, but ...

I disabled password at AP,

wifi_config_t wifi_config = {
.sta = {
.ssid = "MY Wifi",
.password = "",
.threshold.authmode = WIFI_AUTH_OPEN,
.bssid_set = 0,
},
};
