I created a thingspeak account 9 days ago. I have been sending data during 5 days without problems in a thingspeak channel with a ESP32, but since yesterday at 14:28 the channel has stopped receiving any data without me doing anything. I have checked API key, channel ID, client ID and there isn´t any problem with this.
Could you help me, please?

We sent many messages to MQTT users, but since you only signed up recently, you might not have gotten those emails. I apologize for the frustration you feel.
We upgraded our MQTT server in July 2021, and posted about it here.
You can find upgrade instructions at the blog post.
The ThingSpeak community also has a header at the top also warning about the legacy deprecation.
Many examples out in the world wide web have not been updated, but you can use our examples to upgrade your system.
