Backup to Nabu Casa fails: ssl/tls alert bad record mac

Installation Home Assistant OS

I’m having issues with nabu casa backups. As per Backup upload to Home Assistant cloud always fails · Issue #136503 · home-assistant/core · GitHub, the backup is failing to upload. Initialliy it would succeed every few days, but now has been unsuccessful for the last 2 weeks. Full logs on the linked post.

The only other information I have, is I’ve noticed pihole reporting HA is being rate limited because it is issuing over 1000 DNS requests within 60s. I’m not sure why HA would be issuing so many DNS requests, or why that would result in SSL errors.

Any help is appreciated, even if it’s just how to try get more information from the logs.

Looking at the pihole query log, there seems to be something triggering approximately 1000 simultaneous PTR lookups to public IP addresses.

Based on the thread at HA spamming PTR DNS lookups? - #90 by stevebaggs, I’ve disabled the DHCP integration, and the DNS rate limiting issue seems to have gone away, although not sure of the cause.

The backups issue still persists.
