Sounds like a server issue. Enable HTTP logging, then check the desktop debug log for the errors, find the X-Request-ID’s, and grep for them in the owncloud.log.

@michaelstingl Thank you for your insight. I figured it had something to do with server configuration. Alternatively, I created a separate cPanel account in WHM for the subdomain to give ownCloud its own root level folder and account separate from the main website.

This is a better IT practice when installing and using large web applications in subfolders. It resolved the issue without any troubleshooting. Thanks again for your responsive help. It is greatly appreciated. I’ll use this method next time when I have more time to troubleshoot and mitigate impact on operations and staff.

Thanks again,
Dr. Shinshuri
