Hi, With the configuration described few days ago (raspberry behind a SFR box), as the SFR Network seem to work correctly today, I did test a little bit more. It seems that the simulcast « auto » does not work properly. The test has been done with 3 clients : - MacBook on local network Safari/Brave - iPad on local network Safari/Firefox - iPhone in 4G Safari With simulcast « auto » I can connect 2 devices but not 3 with the simulcast « off » the 3 are connecting and work perfectly.
