Activate runners session_server within Docker

Hi,
i have a runner in docker, I want to activate the session_server, but this does not work.

That was my config:

[session_server]
  listen_address = "[::]:8093"
  advertise_address = "runner.example.com:8093"
  session_timeout = 1800

or:

[session_server]
  listen_address = "[::]:8093"
  advertise_address = "<server ip>:8093"
  session_timeout = 1800

container logs:

Configuration loaded                                builds=0 max_builds=2

I then tried listen_address and advertise_address with the ip and the domain, all with the same error

Configuration loaded                                builds=0 max_builds=2
listen_address not defined, metrics & debug endpoints disabled  builds=0 max_builds=2
FATAL: Failed to create session server              builds=0 error=listen tcp <server ip>:8093: bind: cannot assign requested address max_builds=2



I cannot open a terminal from a job because of this

I suspect it is due to listen_address not defined, metrics & debug endpoints disabled, but I have set listen_address in the config as described in the documentation (Advanced configuration | GitLab), which has not helped, or runs into an error with ip or domain

Can anyone tell me what I am doing wrong?
