Fehler: invalid config

[xelarep]

Describe the bug
After moving a MariaDB database (i.e. stopping sql.0, export from current server, import on new server, changing server details in sql.0 instance) from one server to a new one.
The "Verbindung Testen" (Check Connection?) reports

"Fehler; invalid config?"

However everything is OK when saving and closing the settings New data is written to sql.0/database, ECharts can access history data

Expected behavior
"Connection OK" would be fine...

Versions:

• Adapter version: 2.2.0
• JS-Controller version: 5.0.17
• Node version: 18.19.0
• Operating system: Linux 5.10.103-v7l+ #1529 SMP Tue Mar 8 12:24:00 GMT 2022 armv7l GNU/Linux (Raspberry Pi 4)

Ok, 1st try. These are my current settings:

When I pick Test, I get this dialog:

I just switched debug level from info to debug for sql.0. However there are tons of messages, because of my current loggings...

I tried the following:

• stopping sql.0
• switching log level from info to debug
• restarting sql.o
• klicking Teste Verbindung
• stopping sql.0
• switching log level from debug to info
• readout the log

for whatever reason I'm not able to dwnload the log, hoverer I can provide some timestamped screenshots:

Please advise how to get better information...
