DNS status tool reports null on all records

[yusf]

Since some recent update, all DNS records are reported [not set] (or null if viewed in Notifications view) even though they present. The Expected value suggested in my case is also not the right one (main domain instead of selected domain).

I use one domain with automatic DNS provision (Digital Ocean) and one with manual, same problem on both.

Adding to this, records aren't added properly when installing new apps:

I do not have this issue on the latest public stable version. Can you please provide some logs?

[girish]

I would check the following:

1. Is unbound running? You will find this in the Services view.
2. Maybe the DNS API keys are invalid/expired?
3. Any chance outbound UDP requests are blocked? (for DNS)

As @murgero said, can you see the app logs when it's waiting for DNS.

Alright.unbound is not running, log below.

[girish]

@yusf I guess you ran out of disk space at some point. See https://cloudron.io/documentation/troubleshooting/#unbound for how to fix it.

[yusf]

@girish Your guess is entirely correct. I'll try it out.

Edit: Worked. Yay
