[Sebclem]

Can you change the log level to debug, retry and add the more detailed logs here please ?

[Sebclem]

Just to be sure, can you check that it's not the same issue as #201

[jerkelens]

I did check it before posting. I also used an app password that isn't too complex, given older issues. The problem still remains though.

[Sebclem]

Ok, getaddrinfo EAI_AGAIN seams to be related to a DNS lookup time out, can you check that you home assistant host machine can resolve your hostname

[jerkelens]

From the HA box, I can ssh into the cloud storage service. Nothing seems out of the ordinary?

[jerkelens]

Afterwards, the file isn't on the cloud storage. Time is plausible given my internet connection, but the file is nowhere to be found. The addon shows the tar under 'snapshots in nextcloud' though.

In addition, I changed the target folder to just '/hassio/' (no quotes). In the log, it says the folder doensn't exist, but it successfully created it. However, that folder is nowhere to be found either. Upon retrying the backup once again, it says the folder does exist. But I can't find it. I will do some digging.

Last but not least: if i disable the SSL slider, I get a slightly different error:

[jerkelens]

It gets weirder, if i do a manual SCP file copy from within the HA terminal, it works and the file appears. I'm guessing a 'platform not supported' might be plausible? :)

[Sebclem]

I can only test on stock Nextcloud, they maybe change the Nextcloud webdav api

[jerkelens]

Possibly. I asked the platform owners to look into it, figure out where the uploads go. They're working on it and will probably get back to me tomorrow. Thanks for your help so far Sebclem!

[jerkelens]

Hi - so the hosting party figured out where my files went, apparently having a different account there, generates a separate file environment, so currently the export is working.

However, this wasn't always the case, in my troubleshooting I changed to different credentials to validate if my current credentials were causing the issue. Upon this change, it wasn't working, that's when I opened this bug report and the first errors were apparent DNS issues.

At this moment is appears to be working. I have scheduled a daily backup, which is created, should this be uploaded automatically? That for some reason requires my manual intervention, after which is works. Could this be related to this issue?

[Sebclem]

Hi,
The auto backups should create a new backup, and if there is no error, the created backup should be uploaded to nextcloud.

The created backup is no uploaded automatically? Do you have any errors in logs ?

[jerkelens]

Hi Sebclem,

Backups aren't automatically uploaded for me. If I look into the logs, I still see this recurring error:

[error]: Fail to upload snapshot to nextcloud (RequestError: getaddrinfo EAI_AGAIN < MYHOSTHERE >) !

However, I've been looking into the EAI_AGAIN error, I see errors regarding multi-dotted domain names. My host is stackstorage.com and the domain is < account >.stackstorage.com. Does that differ from nextcloud native by any chance and could it somehow be triggering these issues? I am using local DNS logging, tracing the log shows the connection fails most of the time (EAI_AGAIN) and sometimes succeeds. However, if the connection by the addon fails, I am able to execute an SCP to the host at the near same time. I am lost :(

[Sebclem]

You mean your domain is xxxx.stackstorage.com ?
If yes you should not have any issue, just check if in config you don't have a dot on front or at the end

[jerkelens]

Sorry, the parsing of < account > wasn't done right because I didn't use spaces. I indeed have xxxx.stackstorage.com.

[jerkelens]

I did another test: scheduled a backup, it ran but didn't upload. Right afterwards I tried to upload the same file, it worked like a charm. Which I like, but I don't understand why the automated backup generates an EAI_AGAIN, while the manual backup works.

Hi,

This bug can be closed. I tried another addon, that gave an error: "unsupported API response". This indicates that this very nextcloud instance isn't default and I shouldn't expect 100% functionality from an addon. You might however want to filter on nextcloud URL's, just to be sure. Thanks for your assistance!
