Answer:

How to fix a computer that cannot access an IE-only website

If you have ever tried to access a website that only works on Internet Explorer, you may have encountered some frustrating issues. This is especially true for some government websites that have not been updated for a long time and have no support. One example is the website for car tag registration in Puerto Rico, which is https://siscon.hacienda.gobierno.pr/marban/z_container.aspx. This website is essential for auto works businesses that need to register car tags for their customers.

However, some users have reported that they cannot load this website on their computers, even when using Edge in IE-compat mode or other browsers with IE-compat addons. They get an error message that says “the webpage cannot be accessed”. This can be a serious problem for their business, as they cannot complete the registration process and may lose customers.

In this article, I will share some possible solutions that may help you fix this issue and access the website normally. I have tested these solutions on a client’s computer that had the same problem and was able to load the website successfully. However, please note that these solutions may not work for everyone, and you should always back up your data before making any changes to your system.

The first thing you should do is to make sure that your internet connection is working properly and that your firewall is not blocking the website. You can do this by following these steps:

• Open a browser and try to access a different website, such as https://www.google.com. If you can load the website, then your internet connection is fine. If not, then you may have a problem with your network or your internet service provider. You should contact them and ask for assistance.
• If your internet connection is fine, then you should check your firewall settings. A firewall is a software or hardware device that protects your computer from unauthorized access or malicious attacks. However, sometimes it may also block legitimate websites that you want to access. You can check your firewall settings by following these steps:
• On Windows 10, go to Settings > Update & Security > Windows Security > Firewall & network protection.
• On the left pane, click on the network profile that you are using, such as Private network or Public network.
• On the right pane, make sure that the switch for Microsoft Defender Firewall is turned on.
• Click on Allow an app through firewall.
• Click on Change settings and enter your administrator password if prompted.
• Scroll down the list of apps and look for Internet Explorer. Make sure that both the Private and Public boxes are checked for it. If not, check them and click on OK.
• Try to access the website again and see if it works. If not, proceed to the next solution.

Solution 2: Update Internet Explorer and enable compatibility mode

The next thing you should do is to update Internet Explorer to the latest version and enable compatibility mode for the website. Compatibility mode is a feature that allows Internet Explorer to display websites that were designed for older versions of the browser. This may help you load the website that only works on Internet Explorer. You can do this by following these steps:

• On Windows 10, go to Settings > Apps > Apps & features.
• On the right pane, scroll down and look for Internet Explorer 11. Click on it and then click on Modify.
• Follow the instructions on the screen to update Internet Explorer to the latest version. You may need to restart your computer after the update.
• After the update, open Internet Explorer and go to Tools > Compatibility View settings.
• In the Add this website box, type the URL of the website that you want to access, such as https://siscon.hacienda.gobierno.pr/marban/z_container.aspx. Click on Add and then click on Close.
• Try to access the website again and see if it works. If not, proceed to the next solution.

Solution 3: Reset Internet Explorer settings

The last thing you can try is to reset Internet Explorer settings to their default values. This may help you fix any corrupted or misconfigured settings that may prevent you from loading the website. However, this will also delete your browsing history, cookies, passwords, and other data that you may have saved on Internet Explorer. You should only do this as a last resort and after backing up your data. You can do this by following these steps:

• On Windows 10, go to Settings > Apps > Apps & features.
• On the right pane, scroll down and look for Internet Explorer 11. Click on it and then click on Advanced options.
• Click on Reset and then click on Reset again to confirm.
• Wait for the process to complete and then restart your computer.
• Try to access the website again and see if it works.

Conclusion

I hope that one of these solutions helped you fix the issue and access the website that only works on Internet Explorer. If none of them worked, then you may have a more complex problem that requires professional help. You can try to contact the website’s owner or the Puerto Rican government and ask for assistance. You can also try to use a different computer that can load the website and register the car tags for your client. However, this may not be feasible or convenient for your business.

I understand how frustrating it can be to deal with outdated and unsupported websites that are essential for your work. I hope that the website will be updated soon and become compatible with modern browsers. Until then, I wish you good luck and happy browsing. 😊
