Describe the bug

Testing dashboard using the latest version 1.26.0 and managed to create hummingbot-master_bot_conf however when creating instances under master_bot_conf, we are getting RPCClientTimeoutError: Could not connect to.. Please review the connection.

Check dashboard folder, `../hummingbot_files/bots/instance_name/logs/error.log

Note: This seems related to an update from v2 strategy introducing controllers
