Nextcloud AIO failing to connect (but was working fine yesterday)

matthaiduk · March 5, 2025, 4:48pm

Nextcloud AIO not working after working fine yesterday. as best I can tell it is not starting up. Please see below and let me know what additional detail I can provide.

Thanks!

[details=“Support intro”]

Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can.

The Basics

Nextcloud Server version (e.g., 29.x.x):
- Not sure. When I run “occ update:check” I get “occ not found”
Operating system and version (e.g., Ubuntu 24.04):
- 24.04.02 LTS
Web server and version (e.g, Apache 2.4.25):
- “apache2 -v” gets me “version not found”
PHP version (e.g, 8.3):
PHP 8.3.6 (cli) (built: Dec 2 2024 12:36:18) (NTS)*
Is this the first time you’ve seen this error? (Yes / No):
- yes
When did this problem seem to first start?
- over night
Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
- AIO
Are you using CloudfIare, mod_security, or similar? (Yes / No)
- no

Summary of the issue you are facing:

Cannot connect to AIO through the domain. None of the occ commands are working

Log entries

Nextcloud

Please provide the log entries from your Nextcloud log that are generated during the time of problem (via the Copy raw option from Administration settings->Logging screen or from your nextcloud.log located in your data directory). Feel free to use a pastebin/gist service if necessary.

the log in the data directory is empty.

Web Browser

If the problem is related to the Web interface, open your browser inspector Console and Network tabs while refreshing (reloading) and reproducing the problem. Provide any relevant output/errors here that appear.


It appears that nextcloud is not starting.

#### Nextcloud

"occ config:list system" results in Command 'occ' not found, but there are 22 similar ones.

#### Apps

The output of `occ app:list` (if possible).

Get the same message as above for any occ command

jtr · March 5, 2025, 7:54pm

See AIO: How to run occ commands

matthaiduk · March 6, 2025, 3:30am

Thanks, and I apologize for not being clear. Here’s what gets returned:

Error response from daemon: container 867e54fc6c11beae75748dbf61fa36968b7bff9c385329e07d38cdf96fcd4088 is not running

scubamuc · March 6, 2025, 8:04am

I may be completely off track here and this is an assumption… but recently some Cable providers (V) have changed their connection to DSLite (CG-NAT (Carrier Grade Network Address Translation))… check whether this is the case, see 101: Network, domain and DNS

matthaiduk · March 6, 2025, 12:34pm

Appreciate the thought but I have no issues connecting via ssh, and the response in the post above seems to be saying that the nextcloud container won’t start… for some reason.

szaimen · March 6, 2025, 1:09pm

@matthaiduk can you log into the AIO interface usually running on port 8080 and check the state of your installation? Possibly you need to start the containers again?

matthaiduk · March 6, 2025, 2:20pm

Unfortunately no. 8080 gets me the same inability to connect.

Is there a way to restart the containers through the command line? I can give that a try and let you know how it goes

szaimen · March 6, 2025, 2:38pm

Can you post the output of sudo docker inspect nextcloud-aio-mastercontainer here?

matthaiduk · March 7, 2025, 1:58am

@szaimen Absolutely. here you go.

This seems to be the issue why the mastercontainer is not running anymore…

Can you post the output of sudo netstat -tulpn here?

Yes, sir. Here you go:

On a whim, based on the last post by @szaimen I reset the router and switch. All is working fine now.

Thanks so much for the help, everybody!
