Hi,
haven’t been able to connect from tasmota to node02.myqtthub.com via TLS (8883) since April 13th.
It worked before for years, but now it only works w/o TLS (1883).
Are you aware of any specific config/ certificate changes on that date?
Best regards
Yes, I get error code 2 when using TLS since Monday. It worked before and it is working w/o TLS on Port 1883. Did you change sth with TLS on the Server Side? Following the logs, it stopped working on 12th of April at 23:45. BR
It seems, there has been a change to the server/ certificate. I had to reset the Fingerprint on tasmota and now it is working again. Command: MqttFingerprint1 00
This will update the fingerprint on the next connect. Problem solved.
Hello,
Not sure why it is reporting certificate error/mismatch your device. All admision nodes have same front certificate from last 28th March with same serial:

We are happy it is working for you now. Best Regards
