Buffer size error

[thatnovaguy]

I'm unable to access the authelia webui and am getting a buffer size error. Do I need to change my config to what's suggested earlier in the log?

Edit: Simply increasing the buffer size did help with accessing the webui. However, I would still like to know whether the server.buffers.write change is needed.

Just change configuration.yml from

server:
  host: 0.0.0.0
  port: 9091
  path: ""
  read_buffer_size: 4096
  write_buffer_size: 4096
  enable_pprof: false
  enable_expvars: false
  disable_healthcheck: false
  tls:
    key: ""
    certificate: ""

into

server:
  host: 0.0.0.0
  port: 9091
  path: ""
  buffers:
    read: 4096
    write: 4096
  enable_pprof: false
  enable_expvars: false
  disable_healthcheck: false
  tls:
    key: ""
    certificate: ""
