I was voting for you as witness and encountered the following error:
https://beta.steemconnect.com/sign/account-witness-vote?witness=klye&approve=1

I was able to fix it by changing the url so that the parameter value 'approve' to equal 'true' instead of '1'. like this:
https://beta.steemconnect.com/sign/account-witness-vote?witness=klye&approve=true
and the vote completed successfully. Hope this helps. Thank you
