QNAP HBS: WebDAV-Backup error

[stultitiophobia]

all versions above 1.6.2 do not work well with QNAP HBS:

as soon as the HBS-process starts, it at once throws an error.
v.1.6.2 does work flawlessly.

Hey @stultitiophobia !
Is it happening on the 1.6.5 from yesterday too? If so, does the webdav logs show any errors? Could you share them?

[stultitiophobia]

Hi, yes !
That's on 1.6.5, too :(

[stultitiophobia]

Should this bar gone in 1.6.6 ?

ok, checked: it is not :(

hey @stultitiophobia!

could you share the log (or at least its errors) from the Internxt Webdav server? (the docker container logs if you are using docker)

thanks!!

This is the docker log:

Hey @stultitiophobia thanks for the feedback, but so far I haven't been able to identify where that TypeError is coming from. The WebDAV logs don't show anything suspicious, which makes it a bit tricky to track down.

In the meantime, we have just released Internxt CLI & WebDAV v1.6.7, which includes several fixes that could be related to this issue.

Could you please update to v1.6.7 and try the backup again? If it still fails, I would really appreciate it if you could share again both the latest Docker/WebDAV logs and the QNAP error again. Hopefully there will be something different this time that helps us narrow down the root cause.

Thanks for your patience!

Hi, @larryrider
it looks definitively more stable.
sometimes the log shows:
