Why Does Grammarly Not Work With VPN? Here’s What You Need to Know
Grammarly is a go-to tool for writers, students, and professionals who want polished, error-free content. But if you’re using a VPN, you might’ve noticed something strange—Grammarly suddenly stops working or behaves oddly. Why does this happen? And more importantly, is there a way around it?
Before we get into the reasons, here’s a smart move: use a VPN that doesn’t mess with your productivity. VeePN is built for seamless browsing, which means it works smoothly with tools like Grammarly. With AES-256 encryption, No Logs policy, and global server options, VeePN keeps you secure without breaking your workflow. Its diverse server locations allow you to choose where your data is routed, which helps protect user privacy when using writing and editing tools like Grammarly.
Now let’s break down why Grammarly might not play nice with VPNs and what you can do about it.

Grammarly and VPN compatibility issues
Grammarly is an effective tool which assists millions of users to perfect their writing by giving real-time grammatical, spelling and style corrections. Nevertheless, under the odd circumstances of using Grammarly in combination with VPN, most of them face unforeseen compatibility problems. Such issues are usually caused by how VPNs can change your connection to the internet, which may activate protection protocols on Grammarly servers.
Although VPNs are set up to defend user data and strengthen security by encrypting your traffic and disguising your location, in some cases, it may disrupt the way Grammarly handles your requests. Consequently, this may force the users to encounter connection errors, limited access, or limited functionality in using Grammarly with some VPNs. Learning more about these technical disputes is vital to any person, who desires to save his/her data but at the same time, make the maximum use of working with Grammarly.
Allowing users to understand more about how VPNs work, server restrictions, and Grammarly security measures, the user can become better at troubleshooting their problems and continue to have an effective, secure writing experience.
Why Grammarly might stop working with a VPN to protect user data
It is not a spellchecker; Grammarly is a cloud-based Artificial Intelligence (AI) program that continuously talks to its servers. Therefore, when anything breaks or changes that relationship, things can go wrong.
The following are the usual reasons:
🛑IP address conflict or blocking. Grammarly keeps secure sessions, using your IP address. With a VPN your IP address becomes instantly different, even changing to a foreign country. This may activate the security system of Grammarly, which believes that this is a suspicious or unwarranted connection. It is even more likely to happen in case your VPN is using shared IPs or in case other users have been abusing it. Also, Grammarly can detect several shifts in the IP or geolocation misalignment as malicious behavior that will lead to the block of the connection.
🛑Georestrictions or network rules.Grammarly is not georestricted in a technical sense, but its network may act differently depending on the area that you are connecting to. When your VPN passes your traffic through a server in the area where Grammarly notices more abuse or bot activity, you may be blocked, or your connection may lag terribly. The unstable connection of the VPN may also lead to Grammarly failure to connect.
🛑Grammarly servers mistake encrypted traffic. Encrypted traffic makes it hard to see through your traffic, which is excellent when it comes to your privacy, but not every service handles it well. The backend of Grammarly occasionally identifies encrypted connections as possible threats, particularly when a loss of packets or other delays triggered by the VPN exist. Grammarly sends information to the external servers to be analyzed, and VPNs or firewalls can disrupt the process.
🛑Browser extension incompatibility. In case you have the Grammarly and VPN browser extensions operating simultaneously, they may conflict. As an example, your VPN extension may conflict with the way Grammarly injects scripts into pages, which may break it or prevent Grammarly from checking what you write at all.
🛑Firewalls and firewall software. Firewalls and firewall software may block the traffic of Grammarly particularly when certain ports used by Grammarly (e.g. port 80 and port 443) are not accessible. Badly set firewalls can block the communication of Grammarly with its external servers causing it to fail or deny access.
Conclusively, the problems may be caused by blocked connections, unstable networks, wrongly set ports, or due to interference of firewalls and VPNs.
The role of Georestrictions in Grammarly access
The georestrictions may interfere with your access of Grammarly considerably, particularly with the use of a VPN. Grammarly strategically places its servers in different countries in order to abide by regional laws and regulations which implies that a specific geographic location can be blocked by the service.
When using your VPN, you may experience errors or lack of Grammarly features when a server you operate in has restrictions imposed on Grammarly. To overcome geographic limits, switch to another VPN server in another country or even region where Grammarly is not blocked. Alternatively, it is possible to turn off your VPN when working with Grammarly to regain access, however, remember that it can compromise your level of privacy and security.
In other scenarios, the connection of Grammarly can also get interrupted because of problems with browser extensions or other elements such as Microsoft Edge WebView. These issues can be resolved with reinstalling Microsoft Edge WebView or changing your browser extensions.
You should also be aware of the way Grammarly handles user data and what security options are used to secure confidential data. As you keep knowledgeable of these aspects, you will be in a better position to make more informed decisions on how to keep your data secured and at the same time have the privilege of using the features of Grammarly without any interruptions. One of the ways of maximizing both your VPN and Grammarly is balancing user privacy and quality service.
How to fix Grammarly not working with VPN and firewall software
The good news is? There is no need to decide whether to have an online privacy or a functional grammar checker. You only have to make some adjustments, or change to a superior VPN.
This is how you can do it:
✅Change your VPN server.The problem is that Grammarly may not respond to your current server, in this case, connect to another region (which is preferably near your actual location). Other VPN servers are more compatible than others depending on the tool you use.
✅Split tunneling. Use split tunneling — this is where VeePN shines. Using split tunneling, you can choose to leave Grammarly off of your VPN connection and leave the rest of the data secure. In that manner, Grammarly will recognize your actual IP and act as usual, whereas the rest of your online behavior will remain encrypted.
✅Enabling WebRTC (when it is disabled). Some VPNs turn off the WebRTC to avert IP leaks. Nevertheless, Grammarly could use WebRTC to operate properly within some browsers. Look at the possibility of temporarily activating it or setting it up more specifically.
✅Use Grammarly desktop app in case the browser one continues to fail. To install the Grammarly desktop app, click the download button on the Grammarly webpage. It is frequently more compatible with VPNs because it remains beyond the sandbox of the browser extension.
✅Verify the browser configuration and extensions. Ensure that Grammarly is activated in browser settings and browser extensions, particularly when you are working in incognito mode or incognito window.
✅Disable ad blockers or add Grammarly to the whitelist. Ad blockers or other similar add-ons may affect the work of Grammarly. Attempt to turn off ad blockers or add Grammarly to your whitelist of ad blockers to fix connection or script problems.
✅Compatibility with the device and operating system. Make sure the device and the operating system you use are compatible with Grammarly, like Windows or macOS. It is possible to check Grammarly in other devices to identify whether the problem still exists. The last version or the evergreen bootstrapper version of your browser or app is best to have installed to be compatible.
✅Read Grammarly help pages. To learn more and find troubleshooting instructions, see Grammarly official help pages with current solutions and information.
✅Check Grammarly in Microsoft Word. In the case that you have Grammarly in Microsoft Word, its integration can be influenced by VPNs or other settings in the network. You can disable your VPN or change your network settings in case Grammarly does not work on Word.
✅Incognito mode and private browsing mode. In case you are using incognito mode or private browsing mode, keep in mind that some of the extensions such as Grammarly may be turned off by default. To use Grammarly in incognito windows, go to your add-ons or extension settings and enable it.
✅Switch between accounts. If you have more than one account or Grammarly account, then you should ensure that you are using the right one. Conflicts between accounts may create a problem with synchronization or access.
The steps are supposed to assist you to resolve the majority of the problems with Grammarly, VPNs, and browser compatibility.
