I upgraded our Monitor 2023.3.1 server install to 2024.0.1 this morning and am having an issue with the database connection. When I look at Administration/Database the connection looks good, green Nominal for status. But when I try going to any other page, I get 'ArcGIS Monitor Database Connection Failure'.
I have tried the solution from: https://community.esri.com/t5/arcgis-monitor-questions/error-connecting-to-db-after-2024-0-upgrade/m-p/1528236#M2141 but that did not make any change. Also I Unregistered and registered the database again and have the same result.
