I have the occasional 401 error too, but I can not follow your explanation as to why it occurs. As far as I know each channel in a channellist, is on a separate "card"in the server that Provides you,so on switching tv channels it probably can give you a minimal internet connection failure, that leads to a 401 error,I am on a MAC portal too, and since the update in software the 401 error has considerably diminished!
I don't know if my reasoning is exactly correct. There however definitely is an issue, we also get it a lot when watching a channel for an hour or more and then switching to another channel.
We also get it a lot when just watching for a few minutes to even hours, then suddenly, poof: 401.
The whole iptv account / Mac address / etc is used only on this formuler box, nowhere else.
As i said previously, when breaking the connection ("verbinding verbreken" in dutch, "close connection" in english?), Then reconnecting to the portal, everything works again.
Over and over again, this fixes the issue. However, the 401 never ever fixes itself. And should it be normal that this 401 occurs from time to time, then at least the MyTvOnline app should be able to fix it by itself.
I still need to replace our router with another better one. If that doesn't fix anything, i can try a different IPTV app.
Are there any logs being generated, that i can provide? Maybe there's something in there that can provide some additional insights in the issue? Maybe i can raise the log level somehow, so that additional logging is generated?
