Issues with ChangeDetection and UptimeKuma

[Anthony Tran]

Hello,

I am experiencing two issues on my Cloudron VPS.

1. ChangeDetection issue

The ChangeDetection app reports a DNS-related error, even though the DNS configuration appears to be correct and working properly externally.

I have checked the DNS settings and everything seems fine, but the application still reports DNS problems.

2. UptimeKuma issue

UptimeKuma is supposed to be running, but it seems unstable. It is also no longer accessible through its URL, even though it was working correctly before.

At the moment, both applications are having issues simultaneously.

Hello @anthony-tran and welcome to the Cloudron forum

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.
