Maximum number of connections

• Each FileMaker Server and FileMaker Cloud deployment has a maximum number of connections. When the maximum number of connections is reached, additional web users see an error message in the web browser when they try to open the custom app.

• If you think FileMaker Server or FileMaker Cloud has reached the maximum number of connections erroneously, it's possible that a web user has not signed out of the custom app properly. You can wait for the sessions to time out, or close the file to disconnect all users from the custom app, or disconnect specific users using Admin Console. See FileMaker Server Help and FileMaker Cloud Help.

• Web users should avoid opening the same custom app from multiple browser windows or in multiple tabs of the same browser window. Each browser window or tab uses its own connection to FileMaker Server or FileMaker Cloud, which may cause it to reach the connections limit quickly. See Designing a FileMaker WebDirect custom app.
