Failed to handshake client error - can't reach Homey

I got an odd error today.

Suddenly I couldn’t get access to the Homey neither with the app nor via the Web.

I got the message:
“Failed to handshake client”

Have restarted Homey Pro (former version) by removing the cable, but still the same issue.

Could anyone help me what to to?

If removing the Homey and try install it again, will that help? And can I then load the backup that Homey performs every day?

Worth a shot:
@ your phone: Try to open the app whilst the wifi is turned off.
When it’s able to connect using your mobile data connection, you can enable wifi again.

ChatGPT didn’t realise that Homey doesn’t work with self-signed certificates :man_shrugging:t3:
