python3 cli-test.py email@gmail.com password ON

Testing the lib hangs. Upon Ctrl+C the following is shown:

Hm it's hanging during the first SSL login request to MyLeviton. I'm not sure what's different about your networking environment, but something isn't letting the requests through. Could it be a firewall, router, or VPN issue?

bjm904 commented 7 years ago

It does appear to be a ssl issue. I tried curl -v https://my.leviton.com/api

I have not had any issues with other SSL connections. I tired all versions of ssl/tls manually:

curl -v --tlsv1.0 https://my.leviton.com/api curl -v --tlsv1.1 https://my.leviton.com/api curl -v --tlsv1.2 https://my.leviton.com/api curl -v --sslv3 https://my.leviton.com/api

Fixed it. For completeness I'm going to explain what happened.

Turns out it was an issue with my network. MTU got set down to 1480. Setting it to 1500 fixed it. On my Mikrotik RouterOS router, a bridge interface's MTU decreased to 1480 after creating an EOIP tunnel that defaulted to 1480. After setting the EOIP tunnel to use 1500 MTU, the bridge changed to 1500 and everything started working correctly.

Worth noting that I have not noticed any other SSL connections not working on the network during this time. Possibly there is an argument you can add to the network calls that can work around this.

craigjmidwinter commented 6 years ago

interesting. I've got the exact same issue, but MTU is 1500 on the network

tlyakhov commented 6 years ago

Can you connect to https://my.leviton.com/api?

craigjmidwinter commented 6 years ago

Yeah, curling it returns the There is no method to handle GET / response though

tlyakhov commented 6 years ago

And the traceback you're seeing is identical? Hanging on the session.login method?

craigjmidwinter commented 6 years ago

I have no idea what changed but when I tried yesterday it started working
