I hope this message finds you well. I have been using Cursor for coding, but recently, I often encounter the error message “Connection failed. If the problem persists, please check your internet connection or VPN.”
I have thoroughly checked my internet connection and VPN (when applicable), and they are functioning properly. I am wondering whether this is a short - term glitch in the system or if there have been long - term policy changes regarding connections, such as potential restrictions.
This information is crucial for me as it will help me decide whether to continue using Cursor for my coding needs.
Thank you in advance for your attention to this matter and for providing clarification.
Best regards

I just encountered the same error as well. I updated to the latest version as of today (7 Aug) and using the auto model. I have been building the project by this setting for a while. I am not considering other model for the moment while in my project.
Connection failed. If the problem persists, please check your internet connection or VPN
I was using NordVPN, and connected to Japan zone, i am currently in Hong Kong. But then the connection somehow become more frequently failed since Aug 2025. I have found a peer solution that somehow works on my case. https://qiita.com/ChaaaBooo/items/459d5417ff4cf815abce
The solution works on me is that:
I disconnect from NordVPN;
Set the internet connection from HTTP2 to HTTP1.1;
No problem diagnose before or after this fix.
