I added a connection to Yamcs and forgot to specify port 8090. What I got as an error was this: <img width="704" height="207" alt="Image" src="https://github.com/user-attachments/assets/7a652362-e767-46e9-8eb5-c60ae4b89cfd" /> That after I tested the configuration in the data source editor and it said is ok and I can use it.
