Trying to connect to the PostGIS DB for RiverGIS fails with
Couldn't connect to river database: var@localhost Please, check you database connection settings!
This happens despite the DB being connected to/loaded (see screenshot below) and already having loaded a layer from the DB into the currently open project which I can edit without problem.
What am I missing respective what steps can I take to debug this?
Edit: Having tried answer 1, adjusting the the user & db-name to be same as in the documentation does not solve the problem.
System: Win10 / QGIS OsGEO4W / 3.18.3
I'm aware of QGIS - error connection of database in RiverGIS but there the DB doesn't seem to have been connected to...
