If a website does not load, make sure you can load other websites. If other websites load up fine, then it is likely that the website itself is having issues. Check if the site is down on https://downforeveryoneorjustme.com/ or a similar site.
In case the website is online, and you still cannot load it, please check if you get any HTTP(S) Error codes.
You might also be experiencing a speed issue – try to change the endpoint and/or port to fix this. (edited)
