Stale online connections

[oischinger]

Hey there, thanks for this amazing project. Works perfect for me. However I noticed that sometimes the go2rtc web interface shows an "online" connection to a camera from e.g. my mobiule phone's browser even though I closed that tab long time ago and even when put the fone in airplane mode. It seems like this connection is "stale".

I wonder if there's a way to cope with this situation. Any ideas how I could further debug this?

Thanks!

Do you using alpha 11?

[oischinger]

Yes

[AlexxIT]

Are you sure this is connection from your phone and not, for example, Hass, or something else?

[oischinger]

It must be the phone because of the useragent I see under "info"

[AlexxIT]

You need to enable env variable PION_LOG_DEBUG=all

I think I've found a mistake, thanks! Will be fixed in next release. Should work fine in current release with default Hass lovelace card.

[oischinger]

I dont think this is reproducable anymore with the beta. thanks!
