Honeywell TCC: SecureChannelFailure

Recommended Posts

For the last few days have been getting the following repeatedly, with (obviously) no data updating:

2018-02-19 07:36:45 - TCC Login Error: Error: SecureChannelFailure (The authentication or decryption has failed.) [hwstat1]
2018-02-19 07:36:45 - TCC Get Error: Error: SecureChannelFailure (The authentication or decryption has failed.) [hwstat1]

Any thoughts? Thanks!

I have the same issue as well. I was on a previous version, then updated to 0.9.6, updated ISY with the zip file, and still seeing this every 5 mins:

2018-02-19 16:45:48 - TCC Login Error: request started [hwstat1]
2018-02-19 16:45:48 - TCC Get Error: Error: SecureChannelFailure (The authentication or decryption has failed.) [hwstat1]

What OS & mono version are you guys using?  I can't reproduce this.  I can login fine with Windows and Raspbian/Mono 5.8.0.108

I'm guessing your Pi OS / Mono are old and Honeywell updated their website to require a higher level TLS.

You nailed it...upgraded Mono and all is well again.  Thanks for your help!

I was on Mono 4.6.2 and updated to 5.8.0.108, and I'm further along the road, but still not there. Now I'm getting various debug messages about cookies and javascript, and it ends the login process with saying I'm using an unsupported browser. 

Fun stuff. I just spun up this rPi a few months ago, and I'm already way outdated! Maybe I'll just blow it away and re-do it to avoid going down a potential rabbit hole of issues.
