"Can't reach database server or port" Warning while setup database page.

[xgao95]

Hello!
I encountered an issue that warning msg popup like below shown, and I have tried to use 8.0.22 mysql image still doesn't work.
Even though I deleted all volume & image then use the docker-compose shared by you, and also I replace the jdbc driver either, still not work.
Would you pls help to investigate the root cause? Thanks~
