Hi there, there could be a number of reasons why this could happen, dont worry everything is fixable!
1. Have you restarted everything? route, computer?
2. Have you checked the proxy server settings in your browser or application and make sure they’re correct (this is under the settings tab on your computer?
3. Possibly check with your hosting provider? there might be something on their side that is down? or it hasn’t registered your update?
Last resort is to leave it for a while, restart everything and come back? possibly the updates needed a while to configure?
Let me know how you get on!
