Environment Details
- Alteryx Server
- Upgrading from 19.x to 20.x
- User-managed MongoDB (Replica Set)
After upgrading to version 20.x, the AlteryxService will not start. The following errors are found in the Service logs:
MongoConnection.cpp: 16. Mongo error: ""an invalid MongoDB URI was provided"" code: <mongocxx:10>
AlteryxService_LogStartupError: There was an error starting the Alteryx Service <Mongo connection failed, please ensure server address and credentials are correct.>
Cause
If you were using replica sets before the availability of the connection string option (2020.1 release), you have to change to a connection string.
Resolution
Reconfigure the connection string in Alteryx System Settings
(Persistence > General). See this article for details on formatting and connection string examples:
MongoDB Advanced Connection Strings
