A 504 Bad Gateway error when clicking "Continue" typically means the tax website's server is overwhelmed or taking too long to process your return. Try these troubleshooting steps below:
- 504 errors are usually temporary. Wait 15–30 minutes before trying again.
- Open a new browser session in Incognito (Chrome/Edge) or Private (Firefox) mode to rule out extension conflicts.
- Clear your browser’s cache and cookies.
- Switch from Chrome to Firefox/Edge, or use a mobile app/different computer.
- If using WiFi, try switching to mobile data temporarily.
If the issue persists, we suggest you contact our support team at https://turbotax.intuit.ca/tax/software. They have access to tools we don't have here in Community, like screenshare, and can investigate this issue for you.
