Unable to connect Confluence to Google "This app is blocked"

[Thierry Berset]

I am unable to connect Confluence with a Google account.

The use case:

• I insert, on a Confluence page or in a Database, a link to a file stored in Google Drive
• Smart link appears, with the Connect to Google button
• When attempting to connect to the Google account, an error appears:
  This app is blocked. This app tried to access sensitive info in your Google Account. To keep your account safe, Google blocked this access.

This has worked fine earlier in 2025 from a different Atlassian organization.

I have found various Q&As about similar issues and tried the following:

• Delete all Cookies
• Start from a private browser
• Try from a different device where none of the accounts was ever used
• Start from a new user in Confluence that was never connected to any Google account
• Try connecting to a different Google account (none is working)
  • Private Gmail
  • Google Workspace
  • Google Workspace that is connected to a different Atlassian organization and working there
• Change to more secure login (anyway using Passkeys for all users)

I suspect that this could have something to do with Google's changed policy on connecting less secure third apps. But Confluence is supposed to connect based on OAuth 2.0.

I have tried third party apps from the marketplace and they seem to work. However, with some disadvantages, besides the cost.

The functionality that gets completely lost when using apps from the marketplace are Smart links in Databases, which I really started to like.

I am really lost at this moment and welcome any kind of support.

Hello @Thierry Berset 

Welcome to the Atlassian community.

Are you trying to connect to a Google workspace that you administer? If not, contact the administrators of the Google workspace. Perhaps they made a change to block the access as per:

https://support.google.com/a/answer/7281227?hl=en

[Thierry Berset]

Thanks for the quick reply and for pointing directly to the Google support document.

I do have admin permissions in the Google workspace and found the following:

First check under: API controls > App access control > Configured apps - View details

Confluence App is configured for the org, with the following OAuth scope for specific Google data:

• Associate you with your personal info on Google
  openid
• See your primary Google Account email address
  https://www.googleapis.com/auth/userinfo.email
• See your personal info, including any personal info you've made publicly available
  https://www.googleapis.com/auth/userinfo.profile
• See, edit, create and delete all of your Google Drive files
  https://www.googleapis.com/auth/drive

I couldn't find a documentation on the OAuth scopes required by Confluence and instead copied them from the third party App that successfully accesses files in Google Drive.

I could set the App to "Trusted", but I would avoid for permanent operation if possible.

To that point, both Confluence and the third party app are identical.

Second check: Select the App from API controls > App access control

Confluence

• Google sign-in: 0 of 3 scopes granted by users
• Drive: does not appear

Third party app

• Google sign-in: 0 of 3 scopes granted by users
• Drive: 1 of 1 scope granted by users

Third check: My Google account

I am running all trials with my own admin account

Confluence

Does not appear in Third party apps and services

Does not appear in "Recent security activity"

Third-party app

Appears in third-party apps and services

• Drive: granted access
• Google sign-in does not appear

Appears in "Recent security activity"

I have even temporarily allowed "Less secure app access"

Therefore still lost.

It looks to me as if the attempt of Confluence to connect gets blocked right-away, without even leaving a trace.

UPDATE: I got an answer back from Atlassian support! The instructions below-- I've supplemented the provided instructions based on my experience-- worked for me: 

1. (Google Workspace administrator permissions required) Open Google Workspace admin console
2. In the menu on the left, select Security → Access and data control → API controls
3. Select Manage app access in the App access control section
4. Select View list in the Configured apps card (top right)
5. There should be an Atlassian app in this list with the ID 727132345682-9186ghgimhvpp8un6vjb8m9att2a26eu.apps.googleusercontent.com. If it's not in the list, go to step 6. If that app is in the list, select it in the list, click the title of the Access to Google data section at the top, and set to Trusted. 
6. Select Configure new app and search using the above app ID
7. Select the resulting Atlassian app in the list and scope it as needed for your organization. 
8. When you get the Access to Google Data step, set it to Trusted

Allow 10-20 minutes for the operation to sync, then try again.

Also having the same issue (see below). I've tried all the steps that all other folks who have answered in this thread have tried. I'm going to submit an Atlassian support ticket and see what happens... 

[Dragan Markovic]

+1 i have bunch of users who starter reporting this issue, any resolution? 

[Mike Saunt]

Bonjour,

I had this "App is blocks" problem over the last month and tried lots of things with my personal Gmail account and then also as a Google Workspace Admin, I solved it this morning and the following could help.

I went into chrome and deleted ALL site settings for atlassian.net (as neither JIRA or Confluence) would do Smart links.

Also try removing any connections in Google from Atlassian should help as it will re connect anything.

Anyhow, good luck!

Also experiencing this issue trying to oAuth Confluence and Google in order to enable rich Google Drive file previous in Confluence.

I have the same issue. I've tried connecting to my work and my personal google accounts, both are blocked. It is absurd that this doesn't work - I just want to import a google doc as a new confluence page! This is surely a simple request in 2026?

[Travis McCulloch]

I can also confirm the issue - I tried all the steps original poster outlined, same error. As we are trialing Atlassian, we do not have a paid subscription, and cannot open a ticket, I would appreciate the solution passed along to this thread as well. 

Thanks!

[Trudy Claspill]

I don't have any additional expertise to apply to this situation.

Given that this is a user community, this is not the best venue for getting help directly from Atlassian Technical Support.

For any of your that are on paid Atlassian app subscriptions I recommend that you have your Administrator open a support case directly with Atlassian Technical Support on this topic, at

https://support.atlassian.com/contact/#/

Only customers on paid subscriptions will be able to open a ticket through the customer portal.

It would be helpful to the community if your report back here what you learn from Atlassian.

We, as an IT company ha ve a similar problem with multiple users.

Atlassian, could you give us some help with this case?

[IT Testing]

I have a case open with Google that was reviewed by an engineer and their team and its been escalated from there. The engineers didn't see anything configured on the Google Workspace Admin side that would cause the message and confirmed the app is setup properly:

Under Security, API Controls, App Access Control, The Third-Party app Atlassian Cloud is Trusted and configured
Context-Aware Access is Off

I tried this in Atlassian and it didn't work:
Under the user's Atlassian account link preferences, Set default display for new links to Display Card and added an Exception for specific domain

[Jakob Stoeck]

Same issue here. This is likely an issue with Atlassian’s Google App, not a customer configuration issue.

Atlassian has found the same issue before (with a different product, Trello, https://jira.atlassian.com/browse/TRELLO-756), but it seems that it was never fixed: https://community.atlassian.com/forums/Trello-questions/Connecting-Trello-to-Google-Drive-in-blocked/qaa-p/2854431#M101111

Also experiencing this on a newer Google Workspace org. Steps I have tried:

• Private browsing window
• Tried personal and work Google account
• Clear all history/cache/browsing data
• Confirmed with Google Workspace Admin that no 3P apps are blocked
