DNS config error 502 bad gateway notifications

[tecbox]

Since Cloudron 9, I get constantly notifications (messages in message center in Clodron Dashboard) about misconfigured Domain correlated to deSEC DNS:

If I mark as read, the notification is gone and come back around next day, sometimes takes longer, 2-3 days.
I did not find any issues regarding DNS, new Apps and DNS working "normal", nothing I can find in logs.

Logs

If applicable, attach relevant logs from /home/yellowtent/platformdata/logs/box.log or the Dashboard

There is nothing a can share here (didn't find anything).

Troubleshooting Already Performed

Mention any steps you have already tried (restarts, reboots, etc.). This prevents repeated suggestions

Server rebooted, DNS reconfigured, sync DNS, added new App to test DNS record creation. All ok / function.

Hello @tecbox
Without the domain we can not validate the deSEC configuration.

[tecbox]

Hi @james
the domain is "tecbox.de". Thanks!

[james]

Hello @tecbox
Sorry, I mistook deSEC for DNSSEC.

Do you have IPv4 and IPv6 enabled?
Please connect to your Cloudron server with ssh and run the following two commands and share the output:

curl -4 'https://desec.io/api/v1/'

curl -6 'https://desec.io/api/v1/'

[tecbox]

Hi @james,
no problem, here the outputs from requested commands:
4:

{"register":"https://desec.io/api/v1/auth/","login":"https://desec.io/api/v1/auth/login/","reset-password":"https://desec.io/api/v1/auth/account/reset-password/"}

6:

{"register":"https://desec.io/api/v1/auth/","login":"https://desec.io/api/v1/auth/login/","reset-password":"https://desec.io/api/v1/auth/account/reset-password/"}

Hello @tecbox
Could you please go into your deSEC DNS configuration in Cloudron and verify if everything look correct and also if the api token is still valid?

[tecbox]

Hi @james
all seems ok, config is good, token is still valid. DNS updates working, a DNS resync goes through without any errors.

[james]

Hello @tecbox
Could you please contact support@cloudron.io and reference this topic with a link?
We need to look into it a little deeper to get to the root of this issue.
