After the node red is updated to 14.0, mqtt cannot connect to Tencent Cloud, Baidu Cloud and other Internet of Things platforms. It always shows that the connection is in progress and cannot be connected, whether it is certificate authentication or password authentication. Before the update, mqtt can connect normally
，The test shows that the connection of Alibaba Cloud’s Internet of Things platform is normal. I have not used other platforms.
How to downgrade to the previous version?
Nothing to do with home assistant is it?
I don’t know. Homeassistant was also updated this month. The cloud log shows that the connection was abnormal in the morning of the 13th,
You cannot downgrade addons, if that is how you run node red. You can restore a backup from before you updated nr though.
But anyway this seems to be a nr problem, use their support channels.
How can I contact node-red?
