Tyk Dashboard crashed after setting the portal domain

So I set the portal domain to be as the same with the dashboard. Later, I was instructed that it is not permitted to have the portal domain same as the dashboard.

However, now I am left with the below error which does not simply disappear when I reconfigure Tyk.

panic: http: multiple registrations for dashboard.tyk-local.com:3000/

goroutine 1 [running]:

I basically had to drop the Mongo table, and then reconfigure Tyk to get everything back in place.

In Mongo shell:

> use tyk_analytics

switched to db tyk_analytics

> db.dropDatabase();

{ "dropped" : "tyk_analytics", "ok" : 1 }
