The title ⬆️

Change needed after upgrading the MDM Servers to use VRRP 🍄

Edit:

Bit more context, if the mDNS resolution fails the fallback IPv6 will be used to resolve defaultmdm.local but then the certificate won't match, thus resulting in the following error:

2024-07-11 09:50:21,415 :: comms.controller.mdm_agent :: ERROR :: HTTP request failed with error: HTTPSConnectionPool(host='fdbb:1ef7:9d6f:e05d::1', port=5000): Max retries exceeded with url: /public/get_device_config/mesh_conf?device_id=04f021bf893310000000744cf195 (Caused by SSLError(SSLCertVerificationError("hostname 'fdbb:1ef7:9d6f:e05d::1' doesn't match 'defaultmdm.local'")))
