Hi ​@christoffernyborgatbiometriase 

Thank you for reaching out and sharing the details of this issue. While it sounds like your internet connection is stable, this message can occasionally appear due to other factors affecting connectivity between your browser and Lucidchart. Here are some steps you can take to resolve the issue:

1. Try refreshing the page (Ctrl+R or Command+R) to see if it re-establishes the connection. This often clears temporary glitches.

2. Cached files or cookies may occasionally interfere with Lucidchart. Clearing your browser cache and cookies might help resolve the issue.

3. Ensure your browser is updated to the latest version, as older versions may encounter compatibility issues with Lucidchart.

4. Open Lucidchart in an incognito or private browsing session to check if extensions or plugins are causing the issue. If the popup doesn’t appear in incognito mode, try disabling extensions one at a time to identify the culprit.

5. While your internet connection seems fine, network settings like firewalls or proxies might disrupt connectivity with Lucidchart. If possible, test on a different network to rule this out. 

6. If the issue persists, capturing your browser’s console logs can help identify the root cause. Feel free to share the logs with the support team here to investigate further: Submit a request – Lucid.

To access console logs:

• Press Ctrl+Shift+J (Windows) or Command+Option+J (Mac) to open the developer console.
• Screenshot any errors or messages that appear when the popup is displayed.

Please let me know if the issue continues after trying these steps.

I hope that this is helpful.
