Before starting off with the solution, I want to explain what this error means. Cannot parse response means that the web requests made by the website are not interpreted by either the server or Safari browser itself. Such issues are temporary and may go away with a simple device reset or browser restart. However, if the issue persists, you may follow these methods.

Check your Internet Connection

The prime reason why this issue is appearing on your end is because of faulty internet connections. Some websites have features that can show when an internet connection is not available or slow. But some websites may stop working and show a “cannot parse response” error when not connected to the internet.

iPhone has a special feature where you can limit the internet connection to apps. Make sure you have given Safari permissions to access and use the internet.

  1. Open Settings app
  2. Choose Mobile Data settings.
  3. Scroll down and make sure safari has toggle enabled.

Similarly, you can also check the internet connection on a mac computer. You can test run to open any other pages like Google.com to check if the network connection is working.

Clear Cookies and Website Data

Cookies and website data play an important role in the functioning of modern websites. Where the old website does not need to store information on your device, new websites use this method to provide a better and fast experience to their users. But if the stored website data is corrupted, then Safari may throw errors such as Cannot parse response error or can not load the webpage errors.

Here are the steps to clear cookies and websites data on Safari iOS:

  1. Open Settings app
  2. Scroll down and select Safari from the list.
  3. Within Safari setting pages, tap on the Advanced menu.

  5. Swipe left on the website which is causing the problem and hit on Delete button.

Quit and Relaunch Safari

Safari is a browser app made by Apple for iOS and Mac devices. Safari may face some random or vocational bugs here and there. These are unfortunate but not very common and not serious in nature. So force quit the Safari browser and relaunch once again to see if the website is working.

Before force quitting Safari, make sure to save all your pending/unsaved work.

Check DNS and Use Google DNS

Having the “Cannot parse response error” in the Safari browser is very unlikely due to DNS issues but not possible. Since all data traffic goes through the DNS (Domain Name Service) and your ISP (Internet service provider) provides, it is possible that sudden changes or malfunction may result in such errors on your end.

So have a call to your ISP and ask for any DNS problems. In case your ISP insists that there is no problem with DNS, then you may consider using the free Google DNS service which is equally reliable and good.

Here are the steps to use Google DNS on Safari iPhone:

  1. Open Settings app in iPhone
  2. Choose the Wi-Fi menu and select the Wi-Fi you are connected to.
    WiFi connections in iPhone
  3. Scroll down and select the Configure DNS option.

  4. Switch to Manual and add DNS server details.
    Configure DNS Servers Settings in iPhone
  5. Type 8.8.8.8 and 8.8.4.4 as the new DNS server address
  6. Hit on the Save command option.

Just check if this resolves the error in the Safari browser on iPhone.

Similarly, we can also change the DNS settings on Mac computers. However, this setup is network-wide and not just limited to the Safari browser.

Here are the steps to change the DNS server settings in Mac:

  1. Click on the apple logo menu, and choose System Preferences…

    This will open the Preferences window with all the list of options.
  2. Click to open Network preferences.
  3. In the list at the left, select the network connection you want to use (such as Wi-Fi or Ethernet).
  4. Hit on the Advanced command button.
    Advanced Network Settings in Mac
  5. Switch to DNS tab, then click the plus add icon button at the bottom of the DNS Servers list.
  6. Enter the Google DNS Server addresses — 8.8.8.8 and 8.8.4.4
    DNS Servers Settings in Mac Computer
  7. Hit on the OK command button to save the changes.

The newly added DNS server will be active and see if the problem is resolved. Do note and keep a backup of the existing set of DNS servers provided by your ISP just in case.

Try a Different Browser

If the issue of cannot parse response in the Safari browser still exists, then it’s a good idea to switch browsers. Google Chrome and Microsoft Edge are equally good, and such errors are non-existent on these browsers.

The Safari gets automatic security updates, and such issues are addressed by Apple on an urgent basis, till the time the issue is fixed, you may use other browsers to carry on your internet activities.

Bottom Line: Safari cannot parse the response

Cannot parse response in Safari is a common error appearing on iPhone and iPad screens from time to time. If you face the same issues ever again, it’s a good idea to close the browser and restart it.

Since the issues may arise from corrupted website data, users are advised to clear website data, including cache and cookies from time to time to avoid such mishappenings.

Perhaps, you should also consider changing the DNS server address and if still things don’t work, then moving to another browser is the only option.
