I have Nextcloud installed in a Docker container with a nginx proxy running on an Rpi4 and Ubuntu 24.04. I’m getting a repeating error regarding Collabora’s app image not being executable. Here is the error:
`Client error: `GET https://MYIP.ddyns.com/custom_apps/richdocumentscode_arm64/proxy.php?req=/hosting/discovery` resulted in a `400 Bad Request` response: <html><body> <h1>Socket proxy error</h1> <p>Error: appimage_not_executable</p> </body></html>
It appears to be saying the the Collabora app image is not executable. But an ls -la of /var/www/html/custom_apps/richdocumentscode_arm64/collabora/Collabora_Online.AppImage yields:
-rwxr--r-- 1 www-data www-data 250003840 Jun 5 12:15 Collabora_Online.AppImage.
So it is executable by www-data, but not by the group and not by others.
I have tried to just manually chmod the file to 755, so that both group and others can execute, both inside the nextcloud-app and on my Rpi4 host:
Rpi4
chmod +x ~/nextcloud/data/custom_apps/richdocumentscode_arm64/collabora/Collabora_Online.AppImage
and
nextcloud-app container
docker exec -it nextcloud-app bash
chmod +x /var/www/html/custom_apps/richdocumentscode_arm64/collabora/Collabora_Online.AppImage
This change “works” for a few minutes, i.e., the AppImage becomes executable and the error desists. But the change does not persist, and the error returns.
Does anyone have a fix for this? Basic setup information below. Thanks!
