Topic on Extension talk:UniversalLanguageSelector

Recently Chrome browser starts to show me a message for mixed content (HTTP/HTTPS) when I open my private wiki. I've used the inspector and found this error message:

Mixed Content: The page at 'https://my.wiki.com/index.php/Home' was loaded over HTTPS, 
but requested an insecure script 'http://freegeoip.net/shutdown'. 
This request has been blocked; the content must be served over HTTPS.

On http://freegeoip.net/shutdown I found this message:

IMPORTANT - PLEASE UPDATE YOUR API ENDPOINT

This API endpoint is deprecated and has now been shut down. To keep using the freegeoip API, please update your integration
to use the new ipstack API endpoint, designed as a simple drop-in replacement.
You will be required to create an account at https://ipstack.com and obtain an API access key.

For more information on how to upgrade please visit our Github Tutorial at: https://github.com/apilayer/freegeoip#readme

So, according to the information placed on https://freegeoip.app/, my question is: Is it correct to set the relevant variable in the following way?

$wgULSGeoService = 'https://freegeoip.app/json/8.8.8.8?callback=?';

On line 305 of https://github.com/wikimedia/mediawiki-extensions-UniversalLanguageSelector/blob/master/UniversalLanguageSelector.hooks.php, it wrote:

$wgULSGeoService = 'https://freegeoip.net/json/?callback=?';

acutal loading url is like: https://freegeoip.net/json/?callback=jQuery32108xxxxxxxxxxxxxxxxx

I guess the format for freegeoip.app is correct https://freegeoip.app/json/8.8.8.8?callback=?

However, I tried to set $wgULSGeoService, but nothing changed in my wiki. Still loading from the shotdown url. Strange!

Same issue here
