Hi there,
An invalid_grant issue comes from Google themselves, not from us, and is specific to your analytics account. It’s one of the more frustrating errors we have to work with from Google since it’s used for a variety of unrelated errors but generally this is caused by one of the following things:
– You are authenticating in for more than 20 websites. Google themselves has a limit on how many authentications a Google account user can have active for Google Analytics now (not imposed by us, and not related to our update). If you’re using more than 20, you’ll want to either split them between multiple Google accounts, or if you use Google GSuite, each Gsuite account gets 20, so that’s a good way to get around it. This sounds like it might be the cause of your issue.
– Your webserver has a time that is slightly off or not set
– The account you are using did not access GA in 6 months (automatically invalidates the oAuth token)
– Soemone with ownership to your account, or who has ownership of the Google Analytics account you’re authenticating in manually revoked some or all GA authorizations
– The Google account you use, or the one that is the master to the GA account reset their overall Google password (which revokes all GA authorizations)

If you’re not using a single Google account to authenticate into more than 20 websites, feel free to get in touch with us at monsterinsights.com/lite-support/ and we’ll be happy to help assist you track down this issue and make sure it gets resolved for you

Hi there,
It absolutely does work even if you’re over 20. We spent quite a lot of time making MonsterInsights resilient to server outages so even if Google’s auth crashed, you site will still be tracking data in (you just wouldn’t be able to get reports back until Google fixed their server).

Right now your sites are tracking, it’s just on the over limit ones you can’t access reports.
