Mostly got this working. Install the LibreSign App: https://cloud.example.com/settings/apps Search for "libresign" with the top eyeglass icon search. Go to its settings and download the dependancies: https://cloud.example.com/settings/admin/libresign Copy-paste and run the following commands from the settings in the Cloudron Terminal for that app: https://cloud.example.com/settings/admin/libresign occ libresign:install --java occ libresign:install --jsignpdf occ libresign:install --cfssl Ignore the last command it says in settings: occ libresign:configure:cfssl --help, unless you know more about that. Instead, use the button to Generate a Root Certificate, and enter the appropriate values to you in that. For personal Certs, you don't need an Organisation. Everything seems to be working except signature images. If anyone knows why or how to fix that, be greatly appreciated.

Yes that's what I finally figured out too lol. Nextcloud sometimes has terrible documentation

@girish Reinstall fixed it. Now I can view different filetypes in Collabora Online. Thank you!

@warg said in Nextcloud - protocol in admin view is broken: I also found some file called data/nextcloud.log in the filemanager which reports some "message":"Error during app service registration: There can only be one Talk backend" error. Is that file from setup/packaging process? Seems like it's not relevant for monitoring? This can be ignored. It's an upstream bug - https://github.com/nextcloud/server/issues/34919 Also, easily verified: root@9b380172-8da6-44fe-9379-3c5dd9dc5e11:/app/code# cat /app/data/data/nextcloud.log root@9b380172-8da6-44fe-9379-3c5dd9dc5e11:/app/code# php /app/code/occ app:install spreed spreed 16.0.3 installed spreed enabled root@9b380172-8da6-44fe-9379-3c5dd9dc5e11:/app/code# cat /app/data/data/nextcloud.log {"reqId":"jSOaEj74uoZDbWtjYYbF","level":4,"time":"2023-04-30T08:35:33+00:00","remoteAddr":"","user":"--","app":"spreed","method":"","url":"--","message":"Error during app service registration: There can only be one Talk backend","userAgent":"--","version":"26.0.1.1","exception":{"Exception":"RuntimeException","Message":"There can only be one Talk backend","Code":0,"Trace":[{"file":"/app/code/lib/private/AppFramework/Bootstrap/RegistrationContext.php","line":314,"function":"registerTalkBackend","class":"OC\\AppFramework\\Bootstrap\\RegistrationContext","type":"->"},{"file":"/app/data/apps/spreed/lib/AppInfo/Application.php","line":153,"function":"registerTalkBackend","class":"OCP\\AppFramework\\Bootstrap\\IRegistrationContext@anonymous\u0000/app/code/lib/private/AppFramework/Bootstrap/RegistrationContext.php:152$4b","type":"->"},{"file":"/app/code/lib/private/AppFramework/Bootstrap/Coordinator.php","line":142,"function":"register","class":"OCA\\Talk\\AppInfo\\Application","type":"->"},{"file":"/app/code/lib/private/AppFramework/Bootstrap/Coordinator.php","line":94,"function":"registerApps","class":"OC\\AppFramework\\Bootstrap\\Coordinator","type":"->"},{"file":"/app/code/lib/private/Installer.php","line":143,"function":"runLazyRegistration","class":"OC\\AppFramework\\Bootstrap\\Coordinator","type":"->"},{"file":"/app/code/lib/private/legacy/OC_App.php","line":451,"function":"installApp","class":"OC\\Installer","type":"->"},{"file":"/app/code/core/Command/App/Install.php","line":97,"function":"enable","class":"OC_App","type":"->"},{"file":"/app/code/3rdparty/symfony/console/Command/Command.php","line":255,"function":"execute","class":"OC\\Core\\Command\\App\\Install","type":"->"},{"file":"/app/code/3rdparty/symfony/console/Application.php","line":1009,"function":"run","class":"Symfony\\Component\\Console\\Command\\Command","type":"->"},{"file":"/app/code/3rdparty/symfony/console/Application.php","line":273,"function":"doRunCommand","class":"Symfony\\Component\\Console\\Application","type":"->"},{"file":"/app/code/3rdparty/symfony/console/Application.php","line":149,"function":"doRun","class":"Symfony\\Component\\Console\\Application","type":"->"},{"file":"/app/code/lib/private/Console/Application.php","line":215,"function":"run","class":"Symfony\\Component\\Console\\Application","type":"->"},{"file":"/app/code/console.php","line":100,"function":"run","class":"OC\\Console\\Application","type":"->"},{"file":"/app/code/occ","line":11,"args":["/app/code/console.php"],"function":"require_once"}],"File":"/app/code/lib/private/AppFramework/Bootstrap/RegistrationContext.php","Line":461,"message":"Error during app service registration: There can only be one Talk backend","exception":{},"CustomMessage":"Error during app service registration: There can only be one Talk backend"}}

I think https://github.com/strukturag/nextcloud-spreed-signaling is required for this functionality (maybe, not sure).

TBH I don't use the Cloudron Collabora app in Nextcloud. Just the Nextcloud Office App, which us basically the same thing, just one less part to maintain. Since Collabora/Nextcloud Office has improved so much, I don't need or miss Only Office. I think it might have a couple of missing features that Collabora/Nextcloud Office doesn't (less Print Preview options I seem to remember), but I don't miss them.

@jdaviescoates No I haven't got that. I have read that was the "only" client but the "one calendar" android app seems to support caldav too.

@girish i tried using the URL for the roundcube login page, but that doesn't work. I might take a look at the snappymail app suggest by @jdaviescoates

Looks like there is also - https://github.com/nextcloud/twofactor_totp

@fbartels @nebulon I see. I guess Cloudron Email Alias records are stored in the LDAP table then? It would be handy for this integration if they were, just a good time-saver, and implementation consistency in using this provisioning setup tool for larger user groups.

@zylstra did you get to the bottom of this? I see that there was no response upstream as well. It's not very easy to get to the bottom of these things. I think for a start, you can disable most of the plugins and see if the page loads without them.

@yusf Agreed! Needs some campaigning on GitHub probably. You'd think they'd have noticed how close they are to offering an alternative to the fastest growing SaaS app in the same space! No point just trying to match Microsoft for features, as they lag everyone else.

@nebulon This was a strange episode, still unclear what happened, but everything "came back" to normal for some reason.

@zylstra Sometimes it helps to disable unwanted/unused Nextcloud apps.

@marcusquinn maybe this will help https://forum.cloudron.io/post/53660

@girish yay!

@girish Hi, sorry, I wasn't clear, I sent the second message and wanted to indicate that I found the issue and resolved it. The volume wasn't mounted correctly in the fstab.

@jdaviescoates right, we roll out alphabetically as you noticed

@girish awesome! That's what I was looking for there Of course now I've got my shiny new EdgerRouter X setup with hairpin nat and things are working out of the box as expected

I would recommend you to use WebDAV instead of CIFS it will be faster as WebDAV is more modern and appropriate for extended network (non LAN).
