Hi.
I’m stuck with this error (see log below) trying to connect to hivemq.cloud broker using MQTT5.
I used HiveMQ server certificate that I loaded with esp_tls_set_global_ca_store function (being careful to set the use_global_ca_store MQTT client config struct member to true). I didn’t use SSL mutual authentication (so I didn’t use a private key).
Username and password were double checked. I even created another user to be sure that I didn’t make any mistake when copy-pasting. But anyway if it was caused by a wrong password, the error code would have been different (134/0x86).
Does anyone have an idea of what may cause this error ?
Thank you !
Note that I replaced the URI prefix by XXXXXXXXXXXXX in the pasted log output.
