Share your full Traefik static and dynamic config, and docker-compose.yml if used.

Use 3 backticks in front and after code, or select code and press </> button. In yaml every space matters.

Your rule looks completely broken.

[http.routers]
  [http.routers.frps]
    rule = "Host(`proslushka23.com`) || HostRegexp(`{subdomain:[a-z]+}.proslushka23.com`) "
    service = "frps"

[http.routers]
  [http.routers.frps-secure]
    rule = "Host(`proslushka23.com`) || HostRegexp(`{subdomain:[a-z]+}.proslushka23.com`) "
    service = "frps"

can you provide text instead of screenshots?

/etc/traefik/dynamic_conf.toml:

[http.routers]
rule = "Host(`proslushka23.ru`)"
[http.routers.frps]
entryPoints = ["web"]
rule = "Host(`proslushka23.ru`)"

The problem is the field rule in line 2 of your file.

The correction (the indentation is only for the readability):

[http.routers]

    [http.routers.frps]
      entryPoints = ["web"]
      rule = "Host(`proslushka23.ru`)"
      service = "frps"

    [http.routers.frps-secure]
      entryPoints = ["websecure"]
      rule = "Host(`proslushka23.ru`)"
      service = "frps"
      [http.routers.frps-secure.tls]
        certResolver = "le" # From static configuration
      [[http.routers.frps-secure.tls.domains]]
        main = "proslushka23.ru"
        sans = ["*.proslushka23.ru"]

[http.services]
  [http.services.frps.loadBalancer]
    [[http.services.frps.loadBalancer.servers]]
