Can't connect to paper lobby server

[pietru2004]

I can't join my server made on dockers, I have linux mint as core with docker, docker compose and cockpit.

As proxy I use Velocity becose of simple setup.
I have one server cur. it is Paper 1.16.1
code - yml(with removed Unique IDs)

Sorry for this down but it made yml code crazy there.

{
# Config version. Do not change this
config-version = "1.0"

# What port should the proxy be bound to? By default, we'll bind to all addresses on port 25577.
bind = "0.0.0.0:25577"

# What should be the MOTD? This gets displayed when the player adds your server to
# their server list. Legacy color codes and JSON are accepted.
motd = "&3A PerCraft Network"

# What should we display for the maximum number of players? (Velocity does not support a cap
# on the number of players online.)
show-max-players = 100

# Should we authenticate players with Mojang? By default, this is on.
online-mode = true

# Should we forward IP addresses and other data to backend servers?
# Available options:
# - "none":   No forwarding will be done. All players will appear to be connecting from the
#             proxy and will have offline-mode UUIDs.
# - "legacy": Forward player IPs and UUIDs in a BungeeCord-compatible format. Use this if
#             you run servers using Minecraft 1.12 or lower.
# - "modern": Forward player IPs and UUIDs as part of the login process using Velocity's 
#             native forwarding. Only applicable for Minecraft 1.13 or higher.
player-info-forwarding-mode = "LEGACY"

# If you are using modern IP forwarding, configure an unique secret here.
forwarding-secret = ""

# Announce whether or not your server supports Forge. If you run a modded server, we
# suggest turning this on.
announce-forge = false

[servers]
# Configure your servers here. Each key represents the server's name, and the value
# represents the IP address of the server to connect to.
lobby = "lobby:25566"

# In what order we should try servers when a player logs in or is kicked from aserver.
try = [
  "lobby"
]

[forced-hosts]
# Configure your forced hosts here.
"lobby.percraft.otzo.com" = [
  "lobby"
]

[advanced]
# How large a Minecraft packet has to be before we compress it. Setting this to zero will
# compress all packets, and setting it to -1 will disable compression entirely.
compression-threshold = 256

# How much compression should be done (from 0-9). The default is -1, which uses the
# default level of 6.
compression-level = -1

login-ratelimit = 2000

connection-timeout = 5000

# Specify a read timeout for connections here. The default is 30 seconds.

# Enables compatibility with HAProxy.
proxy-protocol = false

[query]
# Whether to enable responding to GameSpy 4 query responses or not.
enabled = true

# If query is enabled, on what port should the query protocol listen on?
port = 25577

# This is the map name that is reported to the query services.
map = "Velocity"

# Whether plugins should be shown in query response by default or not
show-plugins = false

[metrics]
# Whether metrics will be reported to bStats (https://bstats.org).
# bStats collects some basic information, like how many people use Velocity and their
# player count. We recommend keeping bStats enabled, but if you're not comfortable with
# this, you can turn this setting off. There is no performance penalty associated with
# having metrics enabled, and data sent to bStats can't identify your server.
enabled = true

# A unique, anonymous ID to identify this proxy with.
id = ""

log-failure = true
}

All runs with no errors but I can't join server it gives error "Unable to conect to lobby. Try again later."

Did you use a custom server type in order to use Velocity? The provided config is very hard to read. Three back ticks is what you needed for a code block

...also seeing your compose file would be helpful

[pietru2004]

Yes I need to use custom jar for Velocity becose you don't have support build-in unfortunely
And I need to get were is placed docker compose file(If you could tell it would be helpfull)
