safari problem

Hello everyone,


I've been having an annoying problem the past couple of weeks on both my macbook and iphone.

I can't join several websites on both the devices but only when i am connected to my home's wifi network. I get this error: safari can't open the page because safari can't establish a secure connection to the server.

However if i join a different wifi network or use mobile data all websites work perfectly on both my macbook and iphone. I have tried several other non apple devices using my home's wifi and they have no problem.

I tried downloading different browsers but the problem stays.

I have also tried reseting my router but that didn't help.

Anyone got any tips?


Thanks,

Alex

MacBook Pro 13", macOS 10.15

Hi Alex,


  1. Open System Preferences and go to Network;
  2. Click Advanced;
  3. Navigate to the DNS tab and click + button
  4. Enter 8.8.8.8 and hit Enter;
  5. Once again, click + button;
  6. Submit 8.8.4.4 and click Enter afterward;
  7. Hit Ok and Apply buttons


  1. Open the site which shows Safari can't establish a secure connection error;
  2. Navigate to the address bar and click the (Lock icon) Secure button;
  3. Select More information
  4. ick on View Certificate and check which certificate is in use;
  5. Go to Details tab and click Command + Space buttons at the same time;
  6. In the Spotlight Search enter Keychain;
  7. On the left panel select System Roots
  8. Search for the website's certificate;
  9. Click on it and expand Trust section;
  10. On When using this certificate section select Always trust.


Are you running any AntiVirus or Cleaning Apps? Both can cause this.

Hi Aqua,


Thanks for your reply.

I changed my network settings as you said but when i entered a website that i can't join in safari i didn't get the small lock icon on top. It only appears in websites that i can join. So i used a different browser to see which certificate it is. I got the name went back to safari opened a normal website found that certificate and set it always trust but unfortunately that didn't solve the problem.

No I do not use any antivirus or cleaning apps on my mac or iphone.
