XF 2.3 cURL error in admin

[AndreaMarucci]

I've noticed some of these errors in my admin panel. Can someone tell me what's happening?

ErrorException: Push notification failure: cURL error 6: Could not resolve host: permanently-removed.invalid (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://permanently-removed.invalid/fcm/send/fDVj_8MeEiQ:APA91bF_3K8mtDk40nMLrcCK6jeckwTeF7FBRhqn4uMKdGSosLYflaGFp7HRZBi6cLlvr5Yba5apSXVhpbRtaxOpO89mYQSHXrB6866wRfHqO0HEQNgmiWmfNPyhoFh19T-MKMt1ZUAy src/XF/Error.php:81

Follwing the advice from another thread I run that query

SELECT * FROM xf_user_push_subscription WHERE endpoint LIKE 'https://permanently-removed.invalid%'

and removed the only record present. I need to check something more?
