Starting oAuth process returns code 403 (Forbidden)

I want to configure Search Engine Keywords Performance plugin.

Following the steps of “Import Google Search keywords in Matomo” on step 6 “Below Connect Google Account(s), click Start oAuth process” my server returns Code 403: You do not have permission to access this document.

In my server logs I see:

Code 302: POST /index.php?module=SearchEngineKeywordsPerformance&action=forwardToAuth&idSite=1&period=range&date=last7 HTTP/1.0

Code 403: GET /index.php?module=SearchEngineKeywordsPerformance&action=processAuthCode&state=…&code=4/…&scope=profile%20 HTTP/1.0

What can I do?
