### Description

we are running an installation of rocket chat deployed via docker, at the end of April we upgraded to version 7.5.1, using MongoDB 6.0.13, from the admin dashboard I see that the version is supported till November 1st 2025, at the end of may we received an email urging to upgrade to a supported version and since June 1st we are not receiving any push notification, the logs are filled with this:

```auto
