Hi, I have an openstack setup which already has vm's running on it and other external and internal networks. I configured DCN recently adding 2 additional sites and while testing the services, I found I am unable to create external vlan networks for some reason, whereas other networks like geneve are getting created. Horizon is throwing 1 error and that is Internal server error, i am not sure why this happened, or how to solve this issue. Can someone please suggest? With regards, Swogat Pradhan -------------- next part -------------- An HTML attachment was scrubbed...
