OwnCloud backup shows unclear error message

[norbusan]

I have set up aedict to backup user data to my own/nextcloud instance:

Backup storage: owncloud
Owncloud setting
https://...
username/password (application password) entered

I see the folder
Apps / Aedict / backups / UserData
in my cloud, but the actual backup gives the following error:
Failed to create automatic backup: list /Apps/Aedict/backups/Userdata failed: -1 HOST_NOT_AVAILABLE
Going into setting -> User data -> Backup/Restore I see
Failure: list /Apps/Aedict/backups/Userdata failed: -1 HOST_NOT_AVAILABLE

I can confirm that other applications can properly access the server at the same address.

Thanks for letting me know! I have improved the error message reporting in case of backup which will be present in Aedict 3.44.

It may take some time though for Aedict 3.44 to be released. The error is present in your device logs, please check out http://aedict.eu/faq.html the Q: Aedict 3 log section for details on how to see your Android log.

The HOST_NOT_AVAILABLE message occurs either when your phone can't resolve the host name, or on some generic error. The error details are in your phone's log, and will be also shown in the error message produced by Aedict 3.44.

ok here is a log grabbed on the device with catlog

Ah, a bug in official Owncloud client as I suspected:

Caused by: java.lang.ArrayIndexOutOfBoundsException: length=1; index=1 09-26 17:23:43.219 E/Aedict:LoaderEx(23582):

I believe you have your owncloud server at https://foo (that is, there is no path, say, https://foo/owncloud), can you please confirm?

[norbusan]

Yes indeed, my server is at the root cloud.foo.bar/

[mvysny]

Thanks for confirming! It seems that the Owncloud client can't handle when there's no path. I have patched the client to use the root path "/" in that case, let's see whether it will help.

Fixed in Aedict 3.44
