Lately I see that the LanguageTool addon for Google drive is failing to connect
drive.google.com refused to connect.
@dnaber any ideas of what is going on?
Could you post a screenshot of the error you get?
@dnaber here you go:
I can’t reproduce that, but I’ll ask the developer. As a quick workaround, you might want to try our browser add-on (LanguageTool - Online Grammar, Style & Spell Checker), which also works with Google Docs now.
@dnaber I’m using the browser plugin, but I like the docs addon more for a full check ! 
Also I’ve checked the Console after loading the docs addon and it says:
Refused to display in a frame because it set ‘X-Frame-Options’ to ‘sameorigin’.
Also I’ve tryed to test it in Firefox and it works fine.
So your original issue was in Chrome? Which version of Chrome was that?
@dnaber latest
Chrome has been warning about an upcoming update to its security policies, maybe it has finally landed.
Maybe related to this: Chromium Blog: Temporarily rolling back SameSite Cookie Changes
Haven’t found the issue ?
No, your report was the only one so far, and we can’t reproduce it. It might be specific to your setup. Maybe a different add-on, security software or something like that.
I think I’ve found the issue. I has something to do with accounts.
I did uninstall Chrome and reinstall it to see what is going on. Disabled all extensions but nothing it did not work.
But suddenly I discovered a weird behaviour I explain:
I have 3 Google Accounts
Account A: main
Account B
Account C
With a fresh install of Google Chrome in connect and sync Account A
I go to the Google Doc and start the LanguageTool addon: It works right
Then I switch to Account B: same procedure: It works right
Then I go to Account C: and it fails
Note that Account C is the owner of the document.
I’ve tested creating a document with account B and sharing with A and C: Same issue: C has the same error. So is something related to Account C, nothing to do with Chrome or with the other Addons…
Now I’ve uninstalled the LanguageTool from Account C and tried to reinstall… but it simply don’t reinstall. It seems like the installation is binded to Account A exclusively.
Extra testing (I’m writting this as I test):
I’ve logged in with a 4th account, lets say Account D, and it happens the same than with Account.
What has Account B different than C and D? It’s a Google Suite account.
Also I’ve tried opening with Account C and D the extension Code Blocks and it also shows the same error as in Language Tool… It seems that a new Google Chrome policy is blocking other accounts?
Final test:
I’ve tried in a second computer with two Accounts E and F and happens the same
I log in with Account E, install LanguageTool everything fine
Then I log in with Account F in the same document, install LanguageTool and issues start to arise.
So the problem is related with a multiple account issue.
@dnaber additional info:
I’ve tried this also with Firefox and happens the same:
The key is to login in a document with an Google account that is not the default one:
