Cant connect to Supla MQTT Broker

[sskora]

Hello,

I'm using Home Assistant to control my Supla devices. Home Assistant is connected to Supla via Supla MQTT (mqtt25.supla.org). This worked for like 2 months. Since yesterday, I cannot connect to the MQTT Broker.
In my Supla user profile MQTT is activated.
I have tried to disable and enable the broker, generated a new password and tried to connect via MQTT Explorer App on my PC. Neither Home Assistant, nor with my desktop app can I establish a connection to the MQTT broker.

Can someone help me with this?

Best regards
Sebastian
