We have recently upgraded our Alteryx Server from 2024.2 to 2025.1 and are encountering intermittent access issues with the Gallery URL
The server URL is sometimes accessible in Chrome/Incognito, showing the normal Gallery login/home page.
Other times, it displays a "The page you're trying to access does not exist" error, even from the same browser/session.
Server services appear running, but logs show errors like:
16:50:59.468672,ERROR,13,AlteryxServerHost,ErrorHandler,HandleError,4e96b1306812438baa081e03c74e146e,unauthenticated,10.8.1,KL-P-AX,,GET,/gallery/api/status/ping/,,-1,Exception caught by ErrorHandler and marshaled to client,"Alteryx.Server.Common.Exceptions.UnavailableException: The system is currently undergoing maintenance. Please try your request again later.-> at Alteryx.Server.Api.AuthorizationMessageInspector.AfterReceiveRequest(Message& request, IClientChannel channel, InstanceContext instanceContext)-> at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.AfterReceiveRequestCore(MessageRpc& rpc)-> at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage2(MessageRpc& rpc)-> at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage11(MessageRpc& rpc)-> at System.ServiceModel.Dispatcher.MessageRpc.Process(Boolean isOperationContextSet)"
Any ideas to resolve this issue? Thanks in advance!
