Failed to update database "master" because the database is read-only (4371841)

Failed to update database "master" because the database is read-only

In IMOD, you may get this error when attempting to run a sync :

[810143] Database error 3906: Failed to update database "master" because the database is read-only

 

The sync editor is connected directly to the database, instead of connected via the app server.

You can identify which type of connection - in the Sync editor at the very top where you see the connection details (beside 'Synchronization Editor') there will be a long string of numbers and letters, a database reference and port 3342.

When connected correctly via the app server you will see your app server address here.

Connect the sync editor via the App server instead of directly to the database.
