The desktop app signs you in over the internet when it starts. If it cannot reach the MeshInspector servers, the sign-in window shows Connection error with a Retry button and Sign Out, to try another account. The log file of the app may show the same problem as Bad internet connection.
Q1: When I open the desktop application, the error "Connection error" appears, however, I'm sure that my internet connection is stable. What should I do?
A: Start with these steps:
- Double-check Internet Connection: open meshinspector.com in a web browser on the same computer.
- Retry: click Retry in the sign-in window. The app tries to sign you in again.
- Restart the App: close the desktop app and open it again.
- Update the App: make sure you use the latest version from the download page.
If the window says Session expired. Please log in again., the saved sign-in is no longer valid: sign in again. Sign Out in the error window also returns you to the sign-in screen, where you can sign in with another account.
Q2: The app still can't connect. What can I do?
A: Something on your computer or in your network may block the connection:
- Firewall/Antivirus Settings: check your firewall or antivirus software. It might block MeshInspector. Add the app to the exceptions list.
- VPN: if you use a VPN, try to connect without it.
- Proxy and Network Restrictions: MeshInspector has no proxy settings of its own. On a corporate network, ask your IT department to allow HTTPS connections to these hosts:
| Host | What the app uses it for |
|---|---|
| api.meshinspector.com | Sign-in, your plan and the tools it includes, conversion of STEP and other CAD files. |
| app.meshinspector.com | Sign-in in the browser and the web app. |
| meshinspector.com | Help links, the pricing and download pages. |
Q3: Can I work offline?
A: Only with a paid Professional plan. After you have signed in online, the desktop app keeps working without an internet connection for up to 7 days. The trial, Community and Makers plans need a connection every time the app starts. Signing out ends the offline period: the next sign-in needs the internet again. For computers that never go online, see Enterprise.
Q4: I've tried everything, and still have this issue. What's my last resort?
A: If all else fails:
- Contact Support: If the issue persists, reach out to customer support via email at support@meshinspector.com. Attach the log file of the session with the error and a screenshot of the error window.
