403 Forbidden after updt to ver 6

I just upgraded to ver 6 and am now experiencing some networking problems. My DNS servers were 192.168.0.50 (primary) and 192.168.0.60 (backup). After updating I could not access the web interface. I then tried to run pihole -d and had trouble with the Curl command uploading the debug file. So I have temporarily changed my DNS to 192.168.0.1 and was able to successfully upload the diag to tricorder. Could I get some help please?
