"A TLS error occurred" on multiple systems

Hi hermansam,

thank you for clarification. Trying out the MQTT CLI could help narrow down, if the problem lies within the system TLS or the mosquitto library.

Generally the HiveMQ cloud broker is working. TLS errors on different systems suggests that the used certificate is not trusted on those systems.

Try to create the PEM file directly for your endpoint as described in our cloud FAQ: Frequently Asked Questions and please let us know if that worked for you.

Thanks,
Dasha from HiveMQ Team
