Yeesh! I apologize for that. I know exactly what happened there and it's been fixed for a few days now. We had an email outage that lasted a couple of days due to a perfect storm of DNS issues and a change to email providers.
I've got your back. If you have troubles and you're worried about showing up in chat.vivaco.in please feel free to email me [email protected] and I'll do whatever I can to fix things.
Thanks ^_^
