FAQs

I've tried all the solutions and I'm still getting the 'Can't Establish a Secure Connection' error in Safari. What should I do?
If none of the troubleshooting steps worked, the problem likely stems from your network settings, your internet service provider (ISP), or a server-side issue with the website you're trying to access. First, try restarting your modem and router. If the problem persists, contact your ISP to report the issue and check if there are any outages or known problems. If the issue only happens with one specific website, that website may be experiencing problems.
