Unable to install and run

[Cacus3]

I'm encountering a persistent 500 Internal Server Error when accessing the initial setup wizard at http://<IP>:5080/wizard after deploying OnlyOffice DocSpace via Docker Compose. Logs reveal a MySQL connection failure and health check errors that prevent the app from booting properly.

Im instaling by sudo bash docspace-install.sh docker -ep 5080
From https://download.onlyoffice.com/docspace/docspace-install.sh

Environment

• Platform: Ubuntu 22.04 VPS
• Deployment method: docker-compose with official docspace.yml
• ONLYOFFICE version: Latest Docker image as of July 31, 2025
• MySQL version: 8.3.0 (inside Docker)

---

Observed Behavior

When navigating to /wizard, the browser shows:

GET http://<IP>:5080/wizard 500 (Internal Server Error)

Browser console:

Error: An error occurred in the Server Components render.
The specific message is omitted in production builds to avoid leaking sensitive details.

From the container logs (/var/log/onlyoffice/ASC.Web.Studio.log):

MySqlException (0x80004005): Server shutdown in progress
MySqlEndOfStreamException: An incomplete response was received from the server
Health check failed: mysqldb, Status: Unhealthy

---

What I’ve already tried

• Verified that MySQL container is up and accessible (mysql -h onlyoffice-mysql-server -u onlyoffice_user -p)
• Ensured that onlyoffice_user exists and has access from %
• Confirmed from inside the onlyoffice-api container that MySQL connects properly
• Restarted all containers and wiped volumes
• Examined logs from /var/log/onlyoffice/, MySQL, and nginx
• Set in /app/onlyoffice/.env `MYSQL_HOST="onlyoffice-mysql-server"

---

Additional Observations

• The problem occurs before wizard loads — API cannot talk to the database at startup.
• Even though the MySQL service is up, the app logs indicate Server shutdown in progress and an incomplete response.
• Health checks for MySQL seem to fail inside the onlyoffice-api service.
