Hello @anthony-tran and welcome to the Cloudron forum

[OK] box v9.1.6 is running

I can see that you are still on Cloudron version 9.1.6 and your Kernel version is 6.8.0-110-generic which means you are effected by https://forum.cloudron.io/topic/15442/ubuntu-24.04-kernel-6.8.0-110-regression-affecting-cloudron

Please update your Cloudron to version 9.1.7 and report back if this resolved the issue or not.

I have updated Cloudron, but the issues are still present. ChangeDetection still reports DNS errors, and UptimeKuma remains inaccessible from its URL.

Hello @anthony-tran
Aftert the update to 9.1.7 have you tried to restart the server once?
If not, please try.

[Anthony Tran]

I rebooted the server, but I am still experiencing the same issues. I am even reinstalling ChangeDetection to verify, and the problem is still there.

What is strange is that I am still receiving ChangeDetection notifications correctly.

Hello @anthony-tran
What DNS provider are you using and what exactly is the error message from the app affected?

[Anthony Tran]

I’m using Infomaniak as my hosting provider, and they also manage my domain name.

Here is the exact error message:

“An error occurred during the install operation: DNS Error: DNS AAAA Record of change.anthonytran.fr is not synced yet: ETRYAGAIN”

[james]

Hello @anthony-tran
Indeed, the IPv6 records exit.

dig AAAA change.anthonytran.fr +short
2001:1600:13:101::1e95
dig AAAA my.anthonytran.fr +short
2001:1600:13:101::1e95

So this is some DNS issue.
I you run the dig commands from your Cloudron server and from inside the failing apps, do they resolve correctly?

[james]

Hello @anthony-tran
Maybe you can try to disable IPv6 and see if this resolves the issue.
If so, try to enable IPv6 again and see if the issue remains solved or appears again.

[Anthony Tran]

Disabling the PV6 and re-enabling it afterward fixed the DNS issue for changedetection. However, it did not resolve the other issue with uptimeKuma, which still does not open at all.

Hello @anthony-tran
Can you restart the uptimeKuma app and provide us the logs from the web log viewer pasted to https://paste.cloudron.io/ ?
