trying to change the port gives the same error

I'm trying to repeat the guide( https://batoct.com/2020/02/23/low-latency-video-streaming-obs ) with the lowest possible delay via udp from obs to relay monaserver srt, but so far nothing has worked, does anyone have any ideas how to fix this? rtmp =>srt gives too much delay (3 seconds even on a local network
