I have 3 units connecting to a mqtt server
While all connect fine and do there tasks except
as soon as I start a second they all stop working
and constantly reboot never making the connect again until
only one is turned on. it does not matter which one.
more that one causes this
I have tried them in diff rooms all to no avail.
anyone had this issue and how is it fixed
Thanks

I think some MQTT brokers require unique MQTT client names/IDs. See if using different names for each ESP helps.

If this does not work, take a look at the broker server logs to see if there is any reason for the disconnects.
