Hi,

I’m facing an issue with the WebSocket in my application. After some time, I consistently getting a timeout from the event server.

When this happens, any attempts to reconnect to the WebSocket result in a “server error,” and the only way to reestablish the connection is by restarting the event server.

Any ideas?

Hi Anderas,

What version of XProtect (resp Event Server) are you working / testing against ?

The reason I’m asking is because we had similar problem in version 23.3, that have been fixed in 24.1 and 24.2.

It was slightly different than what you describe, but high chance to be the same issue.

Hi,

We are using 2023 R3 with the latest hotfix.

Is it possible to install the 2024 R1 or R2 for the event server and keep the rest of the services with the 2023 R3?

Thanks

Unfortunately, it is not possible to upgrade only the Event Server.

Management Server, Event Server and Smart Client should one and the same version.
