Endless spinning circle opening a document from the CODE owncloud client

[zubanst]

CODE server LOOLWSD 6.4.0 (git hash: 23e6a73) LOKit Collabora Office 6.4-10 (git hash: 8d2f2e3) installed on top of a Ubuntu server 18.04. LOOLWSD server works fine; from a browser I am able to connect to https://pennyitsupport.eu:9980/loleaflet/dist/admin/admin.html. (see screenshots)
Owncloud Collabora online WOPI-like Client 2.3.0 installed on top of Owncloud 10.4.1.3 production environment installed on Ubuntu server 18.04.
The configuration is fine; from the Owncloud web client, click on Office menu shows the list of office like documents recognized. (see screenshot).

**Issue:

Click on any document ends-up with a endless turning circle and the document never opens. Creating a new document, creates the document but never open it with the same endless turning circle.

The log file is attached

When yous say unconfirmed, this means it doesn't happen to others? I can make available a VMware appliance with my installation. Is this a Owncloud client issue? Any feedback wold be appreciated.

This issue does not seem to occur in the CODE 6.4.10 version.

@zubanst, please can you update your CODE version and test again?
