TURN server gives Allocate-request error in logs when trying to screenshare

[tprepper]

When a participant tries to screenshare, this message gets spammed in the logs. Why is that? I have 3478/tcp and 3478/udp open and forwarded, I tried adding user accounts because of the "no such user exists" thing, but nothing seems to be fixing it.

turn ERROR: 2023/01/05 05:50:19 error when handling datagram: failed to handle Allocate-request from xxx.xxx.xxx.xxx:50639: no such user exists cerXXXXXXXXXXXhost (not sure if I should be blanking this out)

I have checked the FAQ https://screego.net/#/faq

• I am using HTTPS to access Screego
• SCREEGO_EXTERNAL_IP is set to my external IP
• Under the room id it says it's using TURN for NAT traversal
• My browser doesn't block WebRTC as screensharing works on other screensharing webapps
• I have reverse proxied 5050 to 443 at the screen subdomain, 3478 udp and tcp is open and the range 50000-55000 is open and set in the configuration.

I have also set the SCREEGO_TRUST_PROXY_HEADERS to true

I am on the same network and IP as the machine that runs Screego, if that matters.

Could you try enabling debug logging via

SCREEGO_LOG_LEVEL=debug

are you setting the X-Real-Ip header in your reverse proxy like it is described in the trust proxy headers setting?

# If reverse proxy headers should be trusted.
# Screego uses ip whitelisting for authentication
# of TURN connections. When behind a proxy the ip is always the proxy server.
# To still allow whitelisting this setting must be enabled and
# the `X-Real-Ip` header must be set by the reverse proxy.
SCREEGO_TRUST_PROXY_HEADERS=false

You could try disabling SCREEGO_TURN_STRICT_AUTH=false if the X-Real-Ip header is set but doesn't work.
