Connection error Gmail with make

Hello @Sovie,
Welcome to the community.
This is not an error this happens with many users due to Google making changes in its API authentication.
As you said there are no issues for you and things are working fine.

“You have until April 2025 to reauthorise your connection” Does it mean that the connection is good till that date?

Yes, the connection is working fine for that particular time. After that just go to the connection page and then reauthorize your connection.

Still recommend you cross-check these posts/help articles which make you more confident about how these things work.
