Unable to receive tickets by email or on customer portal

Unable to receive tickets by email or on customer portal

I created a new support instance yesterday.  I have been able to process inbound tickets from the web form and to be able to create a ticket from within the dashboard.   I have forwarded my company email to the Zoho support email that is assigned within Zoho support email from my instance.

I cannot however not receive any inbound ticket from any email I send to.  I've tried to send to the internal email address and to my support email address (that is forwarded).  No tickets are created.  

I created a customer portal and setup the configuration.  When a customer goes onto the portal and tried to create a ticket, the message is displayed "cannot create a ticket"

Lastly when I try to go and add a new alias I get a message in RED at the top of the screen "Sorry.  Unable to process your request.  Try again later"  This has occurred since I created the new support instance.  

Not sure what I can do at this point to determine the causal of these errors.
