Blank screen - background only when exiting NC Office/Code Server

[n-greene]

Thanks very much for updating CodeServer to be compatible with NC 26. I can confirm that the update worked.

However when I exit out of Collabora to my NC instance I get a blank screen - background only - I have to refresh the browser to get all the other content to display.

I tried clearing cache on the browser as well as update/upgrade/reboot on my instance with same issue repeating after.

Logging: [richdocuments] Error: GuzzleHttp\Exception\ClientException: Client error: GET http://xxxxxxx.net/apps/richdocumentscode/proxy.php?req=/hosting/capabilities resulted in a 404 Not Found response:

404 Not Found

File not found.

Just upgraded to NC26 and build-n Code Server app. Having the same issue. When I click an existing document, a blank page is shown. When refreshing browser(F5), the document shows as you normally would expect. However, edits are not saved.

Edit: And as I'm typing this, it seems that it now(after 15 minutes or so) works better(no F5 needed). FYI: NC is running on fast hardware with SSD storage Still can't edit the(for testing purposes) created documents. There seems to be a permission problem, as I can't delete those documents from NC as well. New documents that I create now seem fine.

[Githopp192]

Nextcloud Server version 26.0.4

Operating system RHEL 8.8

PHP engine version PHP 8.1

Web server Apache (supported)

Database engine version MariaDB

Just did the upgrade of Collabora ONLINE to version: 23.5.202.

After upgrade was completed :

• opening documents (*.xlsx, docx) - getting blank screen (logging in with different user)
• trying to use another browser (i.e. Firefox) - same behave - blank screen
• logging out /logging in / refresh the browser page - same result - blank screen

What i did to solve:

i had to switch between these setting (in fact re-enable the built-in code server):

@n-greene What happens when you visit http://xxxxxxx.net/apps/richdocumentscode/proxy.php?req=/hosting/capabilities directly in your browser? Also, is http://xxxxxxx.net/ the correct URL for your NC or is it supposed to be https://? Also, to clarify

@Yomark1 The reporter is only getting this behavior when they exit. It sounds like you're getting it when you open a document. Your matter may be different.

With HTTPS I get: {"convert-to":{"available":true,"endpoint":"/cool/convert-to"},"hasMobileSupport":true,"hasProxyPrefix":true,"hasTemplateSaveAs":false,"hasTemplateSource":true,"hasZoteroSupport":true,"productName":"Collabora Online Development Edition","productVersion":"23.05.5.3","productVersionHash":"5093121","serverId":"a734ef08"}

It sounds like either your wopi_url or public_wopi_url are incorrect in richdocuments but richdocumentscode is working fine.

You can check for certain the configuration by running occ config:list richdocuments. You can either change the values from the command-line or go Administration settings->Office. If you *Use the built-in CODE" is already selected it will probably be sufficient to toggle it to "Use your own server" then back.
