Failed to connect to mariadb

I tried to connect to mariadb from my computer, but it failed with the following error message.

SqlError: (conn=-1, no: 45028, SQLState: HY000) retrieve connection from pool timeout after 10001ms
     (pool connections: active=0 idle=0 limit=5)
     connection error: Error during pool initialization: (conn=504, no: 45044, SQLState: 08S01) RSA public key is not available client side. Either set option `cachingRsaPublicKey` to indicate public key path, or allow public key retrieval with option `allowPublicKeyRetrieval`
