Error adding Google Calendar

[stevenmcastano]

I'm trying to integrate with a gmail calendar... I've followed the steps for the docker deployment as well as getting the google app credentials which I've put in the proper .env and .end.appStore files... however, when I click to add a calendar... it take me to the google auth screen, let's me pick which google account to use, however.... once I select an account, on redirect it fails, tells me connection refused and I get the following in the logs:

docker-calcom-1  | @calcom/web:start: [next-auth][error][CLIENT_FETCH_ERROR]
docker-calcom-1  | @calcom/web:start: https://next-auth.js.org/errors#client_fetch_error fetch failed {
docker-calcom-1  | @calcom/web:start:   error: {
docker-calcom-1  | @calcom/web:start:     message: 'fetch failed',
docker-calcom-1  | @calcom/web:start:     stack: 'TypeError: fetch failed\n' +
docker-calcom-1  | @calcom/web:start:       '    at Object.fetch (node:internal/deps/undici/undici:11730:11)\n' +
docker-calcom-1  | @calcom/web:start:       '    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)',
docker-calcom-1  | @calcom/web:start:     name: 'TypeError'
docker-calcom-1  | @calcom/web:start:   },
docker-calcom-1  | @calcom/web:start:   url: 'http://localhost:3333/api/auth/csrf',
docker-calcom-1  | @calcom/web:start:   message: 'fetch failed'
docker-calcom-1  | @calcom/web:start: }

And that message seems to repeat itself around once a minute.
