Splunk Phantom: On Phantom: Verify server's 'Allowed IPs' and authorization configuration.

[scc00]

I get this error when i attempt to add a server to the Splunk Phantom App on Splunk Enterprise. I have added the phantom role to the admin role within Splunk Enterprise. I have disabled SSL verification in case that was the issue. There is no network connectivity issues between the servers. But I am still getting this 400 error with no Text context.  I also created a new automation user on the phantom side and applied updated SSL certificates and not there are no SSL errors. Has anyone seen this issue yet? I have it hosted in AWS on EC2 instances sharing the same security groups.

Thanks for responding @phanTom .

I have tried 'any', i've used the internal cidr, single IPs, nothing has worked thus far. It is in the same VPC with a 192.168.* private IP with no public IP. The SG allows all traffic between the private CIDR so there shouldn't be any issue there. How do i adjust the auth.json? I am new to Phantom and it does not allow me to modify it within the account i created.

What kind of red-herring are you thinking?
