Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to this issue.
Please switch to Chrome browser, clear your site cache, make sure you’ve connected the correct Google account, and try re-connecting your Google account with Rank Math by following the steps I’ve mentioned below, without skipping them, and make sure you’ve granted all necessary permissions.
#1 ~ Remove Rank Math’s access from Google
Please remove RankMath’s app from your Google Apps permissions:
https://myaccount.google.com/permissions

#2 ~ Re-connect to regenerate auth token from Google
After that, reconnect the Google account again, to regenerate the auth token from Google, by going to WordPress Dashboard > Rank Math > General Settings > Analytics and configure the Search Console and Analytics settings again:

#3 ~ Grant all necessary permissions
Kindly check all necessary checkboxes to allow Rank Math to access some of the Google Services. Please check my screenshot below for reference:

Let us know how that goes. Looking forward to helping you.
Thank you.
Hello Ike,
Thank you very much for your answer.
I did try again following the steps you mentioned.
Unfortunately, it is still the same: red dot next to “Search Console” and no website in Site field.
Thank you very much for your help.
Best regards.
Update:
I managed to fix the problem by manually adding my website to the Google Search Console.
