Since the last few updates to Safari over the past few weeks. Whenever I play a game on Pogo.com, I keep getting disconnected from the Internet before the game can end. I use a different web browser like Firefox and have no issues at all.

Hey ffmed124,

We'd recommend reviewing this article as it provides steps to help resolve issues specific to Safari: If Safari doesn't open a page or work as expected on your Mac - Apple Support

"Check Safari extensions

If you installed any Safari extensions, turn extensions off. From the menu bar in Safari, choose Safari > Settings (or Preferences). Click Extensions, then deselect each extension to turn it off. Learn more about Safari extensions.

If you find that an extension is causing the issue, make sure that the extension is up to date.

Test with a private window 

A website can store cookies, caches, and other data on your Mac, and issues with that data can affect your use of the website. To prevent the website from using that data, view it in a private window: From the menu bar in Safari, choose File > New Private Window, or press Shift-Command-N.

If that works, use the following steps to remove the website's data, including its caches and cookies. The website can then create new data as needed. If it's a website that you sign in to, make sure that you know your sign-in information before continuing.

1. Choose Safari > Settings (or Preferences), then click Privacy.
2. Click Manage Website Data.
3. Select the affected website from the list shown.
4. Click Remove.
5. Click Done.
6. Open the website again in a non-private browser window.

Check Safari settings

The webpage might not be compatible with one or more browser settings, which you can turn on or off as needed. From the menu bar in Safari, choose Safari > Settings (or Preferences). Then click Websites, Privacy, or Security to access these settings:

• Privacy settings. These settings apply to all websites. For example, a website might require that you allow cross-site tracking, show your IP address, or allow cookies.
• Security settings. These settings apply to all websites. For example, a website might require that you enable JavaScript.
• Websites settings. These settings can be configured for specific websites. For example, a website might require that you allow pop-up windows, allow downloads, allow access to your camera or microphone, or turn off content blockers.

Check iCloud Private Relay

If you subscribe to iCloud+ and are using its Private Relay feature, try reloading the page without Private Relay: From the menu bar in Safari, choose View > Reload and Show IP Address. This menu item appears only when Private Relay is turned on for your network. Learn more about iCloud Private Relay.

Check VPN or other security software

If you installed VPN or other software that monitors or interacts with your network connections, that software could affect your use of the website or the internet. Learn about network issues related to VPN and other software. 

Check network settings

Certain network settings, such as custom proxy settings or custom DNS settings, can affect access to content on the internet. Even if you haven't changed these or other network settings yourself, you might have installed software that changed them for you. 

To find out whether the issue is with the network settings on your Mac, try viewing the page from a different web browser or different device on the same network. Or reset your network settings by setting up a new network location on your Mac.

If the issue affects other devices and web browsers on the same network, the issue is probably with the website, and you should contact the website developer for help.

• If the issue continues to affect only a particular webpage, contact the website developer for help.
• Learn how to block pop-up ads and windows in Safari.
• Learn what to do if your iCloud or Safari bookmarks aren't syncing."

Thanks!

Hello ffmed124,

Thank you for posting to Apple Support Communities.

A new macOS software update can help you with getting this corrected. Software updates contain the latest bug fixes and can assist with Safari and slowness.

Please be sure to back up your Mac first. Use the steps below to back up and update:

Before installing new software, it's a good idea to back up your Mac. If you have an external storage device, you can use it to back up your Mac with Time Machine.

Use Software Update

To check for new software, open Software Update. It's in System Settings (or System Preferences), which you can open from the Apple menu  in the corner of your screen:

* Choose Apple menu  > System Settings. Click General on the left side of the System Settings window, then click Software Update on the right.

* Or choose Apple menu  > System Preferences, then click Software Update.

If Software Update finds new software, click the button to install it. You will be asked to enter your administrator password. During installation, your Mac might show a progress bar or blank screen several times, and you should avoid putting it to sleep or closing its lid.

If Software Update says that your Mac is up to date, then no new software is currently available for your Mac model. Software Update shows only software that is compatible with your Mac.

Take care.
