[steveklise]

getaddrinfo EAI_AGAIN ap.cloudflare.com

I changed my router out for a new'er one, and I'm doing DHCP. I am unable to install an ubuntu apps, and fails on name resolution.

Any help.. mucho appreciated

Which version of Cloudron are you running? Also can you resolve other domains like if you run host cloudron.io via SSH on your server?

Further what to you mean with ubuntu apps in this context?

[steveklise]

v7.7.2 (Ubuntu 22.04.4 LTS)

sklise@ubuntu22:~$ host cloudron.io
Host cloudron.io not found: 2(SERVFAIL)

If I do anything via the gui, i get the above error. I believe its a DNS, or gateway issue

@steveklise Can you check in Services -> Unbound if that is running ? You can also run cloudron-support --troubleshoot on the server.

[steveklise]

unbound is in restart/circling mode. sklise@ubuntu22:~$ sudo cloudron-support --troubleshoot
[sudo] password for sklise:
[OK] node version is correct
[OK] docker is running
[OK] MySQL is running
[OK] nginx is running
[OK] box is running
[OK] unbound is running
[FAIL] Could not load dashboard domain.
Maybe cloudflare proxying is not working. Delete the domain in Cloudflare dashboard and re-add it. This sometimes re-establishes the proxying

@steveklise Looks like unbound came up fine now. Do you have a static or dynamic IP? Do you have Cloudflare proxying enabled? Can you disable Cloudflare proxying and check if it works with that?

[steveklise]

I have dynamic, and yes, i have cloudflare proxy enabled, but i disabled (never had to disable in the past fwiw). Same, the service is spinning. here is the log if of any value

@steveklise said in changed routers/IPs and name resolution isn't working getaddrinfo EAI_AGAIN ap.cloudflare.com:

It's not able to get DNSSEC root keys for some reason. You can try disabling it - https://docs.cloudron.io/networking/#dns . You can also forward all unbound DNS requests to 1.1.1.1 - https://docs.cloudron.io/troubleshooting/#unbound .

i think the unbound DNS worked; seems ok now. thanks!!
