Every time I start up Mathematica, I am greeted with the following message:

ChannelListen::subx: Failed to subscribe to the channel
mqtts://channelbroker-mqtt.wolframcloud.com:8883/users/[email protected]/ChatInvitations.
The channel may not exist or you may not have access to it.

It appears three times; then the message is shut off:

General::stop: Further output of ChannelListen::subx will be suppressed during this calculation.

I don't have much experience with / never use Wolfram Cloud, so I don't really care whether or not I'm subscribed to it. I'm just slightly annoyed by these messages every time I start Mathematica. Is there a way to correct the issue causing them or simply turn them off for good?

Thanks!

One can run the code DeleteChannel[All] to delete all the channels you had created. That's the way I did not long ago, and the messages were turned off then.

The problem occurred when I was curious about a blog mentioned it, and I did that by doing so: 文件(file)->新建(new)->聊天会话.... And from then on, I was the same as you.the position

Another method for avoiding the message is just use Off function, in which you can specify not to show the messages about channels at all.

If you want to delete a specific channel, you can see the document of the function DeleteChannel.

  • $\begingroup$ Thanks! It seems the problem on my end managed to fix itself, however, because I've not seen that error recently. But if it ever reappears, I'll know what to do! $\endgroup$
