I’m trying to add IFTTT integration from the HA console. I get the “Set up the IFTTT Webhook Applet” pop-up, and when I click Submit I get “Unknown error occurred. Are you sure you want to set up IFTTT?”
The HA log is below. Any idea how I can fix this? I’m running HA 2021.7.4 in a docker container on Lubuntu. I use an SSL connection for HA on the default port 443 (with a LetsEncrypt certificate)
