502: Bad Gateway

I have Hassio in docker on Ubuntu server.
I installed Esphome in Hassio but when I launch the WebUi I get:
502: Bad Gateway
In the LOG I get this error


[17:08:10] INFO: Waiting for dashboard to come up…
[17:08:10] INFO: Starting NGINX…
nginx: [emerg] open() “/proc/1/fd/1” failed (13: Permission denied)"


I’m not used to Linux so I’m completely lost.
I tried the two different config for Esphome SSH true or false but same result.

Can you help me getting this thing work?

Thanks

Me too.

You enabled encrypted connections using the “ssl”: true option.
[14:56:19] FATAL: However, the SSL files ‘/ssl/fullchain.pem’ and ‘/ssl/privkey.pem’
[14:56:19] FATAL: were not found. If you’re using Hass.io on your local network and don’t want
[14:56:19] FATAL: to encrypt connections to the ESPHome dashboard, you can manually disable
[14:56:19] FATAL: SSL by setting “ssl” to false."
