How to Fix ‘Can’t Establish Secure Connection Error’ Issue in Safari Browser – Guide
Safari is the browser that iOS and macOS users can trust while surfing online. It has some security features and built-in features that prevent unsafe website loading. It’s a way to remind people about possible security and malware issues. You can be careful online when Safari reminds you to check your connection.
However, when Safari cannot verify this fact, it automatically calls the site dangerous and loads a warning message in the browser. Encryption is important here because protecting your privacy and security is crucial if you want to avoid issues like Safari errors.
DNS ISPs
Click on the Apple icon and choose System Preferences. Then click on the Network icon and choose Advanced. Click the DNS tab and remove all entries from the left pane, click the + symbol and add 8.8.8.8, then click the plus symbol again to add 8.8.4.4.
Weak Encryption
When weak encryption is detected, Safari is immediately disconnected from the connection (it has yet to be determined which detects weak encryption first between Safari and the Mac system). But we all know that, for our privacy and security, websites must be coupled with strong encryption before a web connection can be established unconditionally. This was especially emphasized after the efforts of OS X Yosemite (Version 10.10.4) and iOS 8.4 were enhanced with extra security enhancements. So once the weak encryptions (or whatever the system assumes to be weak) are met, Safari won’t be able to connect. This is how the “Safari cannot establish a secure connection to the server” error occurs.
Then open the keyring. You can do this by clicking CMD + Spacebar; then enter “Keychain”. OR go to Utilities and access Keys from there.
Then click on the system roots for all entries. You will find your certificate here and it will have a blue cross marked on it. Double click on it and another window will appear. up. You have the option to choose a system setting, always approve or always reject.
You will notice that the problem was the certificate all along. Typically, a certificate will be blocked on the email server and will prevent any other website from using it. (Your email server should be the entry starting with the prefix “smtp” and ending with a suffix “.dk.” Why the certificate would be blocked for the email server is as good as you can imagine.
Change certificate authentication to “System Configuration”
Here it is! All the pages you need will load seamlessly in Safari. Problem solved.
antivirus
if you are not up for the task of tinkering with certificates, it might be a good idea to first check the antivirus installed on your machine. Typically, Avast is a notorious culprit on this front. Turn off Web Shield and see what happens. Safari will likely instantly connect to previously banned websites. You will be up and working, but still, there’s no explanation why Safari ran before and stopped all of a sudden. Good luck with that.
IPv6
If option 2 still hasn’t worked for you and you don’t want to delve into certificates and stuff, try isolating the device from the wi-fi network you’re using. Connect it to another Wi-Fi network and see if everything opens perfectly. If you can connect to all sites, including previously blocked ones, turn IPv6 off on your router (if available) and via System Preferences -> Network -> Your Network -> Advanced -> Disable IPv6 from here by selecting it as “Manually”
