Trouble connecting Google Sheets to N8N on localhost - any solutions?

Hey everyone, I’m having a real headache trying to get Google Sheets working with my N8N setup on localhost. I’ve followed all the steps I could find online, but it’s just not clicking. Has anyone else run into this problem? Maybe I’m missing something obvious, but I’m stumped. Any tips or tricks would be super helpful. I’m using the latest version of N8N if that matters. Thanks in advance for any help you can give!

hey, have u tried checkin ur internet connection? sometimes thats the culprit. also, make sure ur using the right Google account credentials. i had issues cuz i was logged into the wrong account lol. if that doesn’t work, maybe try uninstalling and reinstalling n8n? that fixed it for me once.

I’ve been there, and it can be frustrating. One thing that worked for me was double-checking the OAuth 2.0 credentials. Make sure you’ve set up the Google Cloud project correctly and enabled the necessary APIs. Also, verify that your redirect URI is exactly right - even a tiny typo can cause issues.

Another potential gotcha is the localhost security settings. Some browsers are extra cautious with localhost connections. Try using a tool like ngrok to create a secure tunnel to your localhost. This can sometimes bypass those pesky local security restrictions.

Lastly, clear your browser cache and cookies related to Google authentication. Sometimes old data can interfere with the connection process. If all else fails, setting up a fresh Google Cloud project from scratch might do the trick. It’s a bit of a pain, but it’s solved similar issues for me in the past.

I encountered a similar issue when setting up Google Sheets with N8N on localhost. One crucial step that’s often overlooked is ensuring your Google Cloud Console project has the correct API scopes enabled. Specifically, make sure you’ve activated both the Google Sheets API and the Google Drive API.

Additionally, check your firewall settings. Sometimes, they can interfere with localhost connections. Temporarily disabling the firewall or adding an exception for N8N might resolve the issue.

If you’re still stuck, try using a different port for your localhost setup. I’ve found that occasionally, changing from the default port to something like 5678 can inexplicably fix connection problems.

Lastly, don’t forget to restart your N8N instance after making any changes. It’s a simple step, but it can often be the key to getting things working smoothly.
