@trinsec Marathon's embeded video gives me same error as trinsec is seeing.. this is interesting since marathon himself doesnt get the error and he is on QOTO with us, im not sure why it would work for just him off hand... id be curious to try this with other instances or to even see if users at other instances can see that video embedded from qoto.

marathon are you using the default QOTO web theme or one of the other custom ones maybe? Not sure that would matter but only difference i could think of off hand.
