Asterisk / Web Terminal apps installing issue

Hi!
I have a VM with HA OS and I have a problems with installing of Asterisk and Advanced SSH & Web Terminal. Tried to reinstall HA completely, but thats didnt help.
So I trying to save a simpliest version of configuration for both of these apps and getting “Failed to save: Unknown error, see supervisor logs”. First, i tried to install Asterisk and when I got this error, I thought that the problem was in wrong configuration of the app, but then I got this error with SSH Terminal app - all you have to do with configuration of this app is type login / password…so I’m out of ideas.
Asterisk is more important for me, but I’ll start with SSH Terminal, because it’s configuration much easier:

ssh:
  username: my_HA_account_nickname
  password: my_HA_account_password
  authorized_keys: []
  sftp: false
  compatibility_mode: false
  allow_agent_forwarding: false
  allow_remote_port_forwarding: false
  allow_tcp_forwarding: false
zsh: true
share_sessions: false
packages: []
init_commands: []

Thats the error I got when I trying to save:

Thats the errors I got in superviser logs:

Asterisk simpliest configuration (not sure thats everything is right):

ami_password: my_super_duper_secret_password
auto_add: true
auto_add_secret: "my_super_duper_secret_password"
video_support: false
register_ingress_entry: true
generate_ssl_cert: true
certfile: fullchain.pem
keyfile: privkey.pem
additional_sounds: []
mailbox: false
mailbox_port: 12345
mailbox_password: ""
mailbox_extension: "100"
mailbox_google_api_key: ""
log_level: info

Have no SSL certificates, so set generate to true.

Thank you, have tried, but no luck…
Did:

ha supervisor repair
ha dns info
ha dns update

No updates available. There really was no servers in dns info, so I added it:


Later also tried to add 212 and 78 dns’s, its were default in HA.
But after restarting HA OS, nothing changed - still cant install Asterisk or WEB Terminal.
Any other ideas?
Is it really fundamental HA problem and I just need to wait for the update which will fix this? :confused:
