XF 2.3 Push notification failure: cURL error 6

[Bluemoon]

Over the past week, I've started getting a lot of these errors in my error log (around 25 a day). Any idea what is causing them, and how I can resolve it?

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/c54F3Ap631k:APA91bEoYyARSbTQVvIcw-QnX3Of9ZBh1RJEOUwskCnBjdW8bqcVAiSpFyUgE4OL_FEedZF14QtKvLCjj7y3ToOXhjVVPTrJYkRsyt7pR7fVkksAS_lIR4ZEVuq5eqCxID9d_VgrHUS3 src/XF/Error.php:81

I also encountered the same errors literally today.

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

Does that return results?
If so, delete the records - those are invalid / removed push subscriptions.

Thank you, much appreciated! Have done that and will see if it stops the error messages.
