Unexpected SSLError

[avarudkar]

I have been using pywit for a couple of weeks. It was working fine till now. However, today it gave me an unexpected "bad handshake" error. I tried regenerating my access token and working with the fresh one, but the error recurs.

Code and error:
client = Wit(access_token)
client.message('what is the weather in london?')

More info:
Python version 2.7.14
Wit Version: 5.1.0

Any ideas on why this is happening suddenly?

hi @avarudkar, I cannot reproduce your issue using pywit 5.1.0.

For reference, here is my code:

import wit
client = wit.Wit(access_token=MY_TOKEN)
print(client.message('fly from sfo to nyc'))

Did anything change on your side? Is the issue resolved? If not, please comment back, thank you

[avarudkar]

hi @blandinw I am not sure what the problem is. Something may have changed on my side, but I haven't updated any packages or anything lately. I tried to run the code again this morning, but it gave me the same error. I will work with my system admin to find out if anything has changed at their end (although I highly doubt that). I will report back if it is resolved at my end. Thanks for responding!

Just thinking out loud: could there be a compatibility issue with the API version? Pywit is 20160516, but my app is at 20180510.
