Hi Jay
I had the same on OH2.5 M2. I did the following in PaperUI
- Disable Certificat Pinning
- Disable Public key Pinning
- Remove both hash-values (Certificates and public key hash)
further more I had a wrong Username and Password in my config of the mqtt-broker-thing. It always takes a wrong one whenever I make a config
hope this helps
Best
