Missing Web connection on matlab 2023a install Mac M1

My University just gave me a new macbook pro with M1 chip. The install for my matlab licence went smoothly except for the missing Web connection button. see below .. I had the same version of matlab (2023a) on my previous macbook (intel chip) with no internet connection issues. I've tried uninstalling and reinstalling but get the same result. Does anyone have any ideas? I haven't been able to get any help from the University IT department since January. I'm beyond frustrated. Would welcome any advice.

Hi Melanie,

I understand that you are facing issues while trying to connect to the web from MATLAB. Here are some reasons along with the fixes that you can try to resolve this issue: 

• Antivirus Software: Update your antivirus software: Ensure that your antivirus is up to date with the latest virus definitions and software updates. Sometimes outdated antivirus can cause false positives. This will most likely require speaking with your internal IT. 
• Proxy: The MathWorks installer, activation client and while connecting to the web will try to automatically inherit your user proxy settings on Windows and MacOS. 

To disable your Proxy in Internet Explorer: 

1. Click the Tools button and then select Internet Options. 
2. Click the Connections tab and then select LAN settings. 
3. Uncheck the check box for Use a proxy server for your LAN. 

To disable your Proxy in Chrome: 

1. Open the Customize and Control Google Chrome menu by clicking on the three-dots icon at the top right of Google Chrome, select Settings on the right, find Advanced and finally select open proxy settings. 
2. Select the LAN Settings button. 
3. Deselect the checkbox for Use a proxy server for your LAN. 

To disable your Proxy in Safari: 

1. Go to Menu and click on Preferences from the drop-down menu. 
2. Select the Advanced tab and then click on the Change Settings button. 
3. Deselect the checkbox for Use a proxy server for your LAN. 

To disable your Proxy in Firefox: 

1. Click the Tools button and select Options. 
2. Go to the Advanced panel and select the Network tab. 
3. Click on Settings in the Connection Section and select No Proxy. 

You will need to contact your IT Help Desk to troubleshoot this issue if you don't know your proxy settings or the error persists after entering your proxy settings. 

 

• Firewall: You will need to contact your IT Help Desk if your organization is running a network firewall to configure it to bypass blocked connections to the MathWorks servers. Your firewall needs to bypass blocked connections for both addresses over both ports 80 and 443. 
• Date and Time: If the date and time of your computer is wrong, you may encounter a "Connection Error" after clicking next on the destination screen while connecting to internet. To fix this issue, change the date and time on your computer to the correct date and time. 

Hope this helps!
