it worked out! However, now the solenoid-ui is unable to connect to the selenoid

gean@vmi513003:~$ docker logs selenoid-ui
2021/05/03 15:17:21 [INIT] [Reading users from /etc/selenoid-ui/users.htpasswd]
2021/05/03 15:17:21 [INIT] [Listening on :8080]
2021/05/03 15:18:53 [ERROR] [Can't get status: Get "http://localhost:4444/status": dial tcp 127.0.0.1:4444: connect: connection refused]
2021/05/03 15:18:53 Client added. 1 registered clients
2021/05/03 15:18:53 Client added. 2 registered clients

ok, there is another mistake should be:
--selenoid-uri http://selenoid:4444

need to change the uri ,?
--selenoid-uri http: // selenoid: 4444
how can I solve?
