Internal Server Error Docker on Synology NAS

Hello Forum,

I am running Nextcloud on a Synology NAS in a Docker container in combination with a MariaDB database in a second Docker container.

When I try to log in I get the following message:
Internal Server Error

The server encountered an internal error and was unable to complete your request.
Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the server log.

The following can often be found in the log file:
An exception occurred while executing a query: SQLSTATE[HY000]: General error: 4047 InnoDB refuses to write tables with ROW_FORMAT=COMPRESSED or KEY_BLOCK_SIZE.

What can I do to solve the problem? Or if not so simple: In which domain should I continue to search for errors?

Thanks in advance!
