Issue pulling custom app from registry on the same cloudron

[james]

Hello @mathieuepitech
Can you give me the output of the following command on your system?

uname -nar

We found systems with kernel version <110 are not effected.

Yes I have kernel 110.

 6.8.0-110-generic #110-Ubuntu SMP PREEMPT_DYNAMIC Thu Mar 19 15:09:20 UTC 2026 x86_64 x86_64 x86_64 GNU/Linux

But I tried the fixed from here, but I still got the issue.
Should I contact the support ?

Hello @mathieuepitech
Can you also try to apply this patch https://git.cloudron.io/platform/box/-/commit/bffc97ab2fedb06100bc507abd0f8b42d343ea6e
and restart the cloudron-firewall service with:

systemctl restart cloudron-firewall.service

[vk182]

@james thanks for the speed! This one has worked just fine for us!

Hello @vk182
Great to read!

@james Unfortunately on my side it didn't works.
Now the command cloudron-support --troubleshoot get everything ok.
But I still cannot update my custom app from an image that is stored in a custom registry on the same cloudron server.

I even try to reboot my server and that didn't change anything.

Hello @mathieuepitech

Can you please run the following commands:

# first one
curl 127.0.0.1
# second one
curl 127.0.0.1

If the second curl fails there is still a networking issue.

[mathieuepitech]

@james I get an HTML page with Cloudron - Not Found error on both curl

Hello @mathieuepitech

Okay, so the network issue is resolved by the applied patch.
When you configure your docker registry in the Cloudron Dashboard, is there any error when saving?

My bad, with the issue, I had remove the registry and couldn't add it back.
Now I have added back and it's working perfectly.

Thank you very much !

Hello @mathieuepitech
Glad to read that.
So it was indeed also the Ubuntu Kernel 110 issue.
