Elasticsearch 7.17.28 Critical Bugs

Anyone still using Elasticsearch 7.17.28
I'm facing some issues and would like to see if it's a elasticsearch issue or something else

Issues like

  1. Snapshot repo permission issue

Desc:
Elasticsearch loses repo access and gains it automatically after some time causing missed snapshots

  1. Client side connection dropping needing restart which further causes downtimes

if anyone faced similar or any elasticsearch side issue in this version (7.17.28)

Do share please
