I missed the real exception in the wrong file.

I have a Oracle Cloud Always Free Account.
I can create a database with Apex. But i am not able to create a VCN or a Compute Instance. I always get this error: Count of total IPv6 CIDRs exceeds max limit: 0
I tried everything, with the help of the wizards and without.
I already found the same issue on stackoverflow. But the solution didn't work for me.
Region: eu-frankfurt-1
Looks like this should be fixed now.

I want to omitempty always without having to write json:",omitempty" everywhere. Is this possible by some config of encoding/json?
Is this possible by some config of encoding/json?
No.
But you could implement your encoder via the JSON marshaling interface:
type Marshaler interface {
MarshalJSON() ([]byte, error)
}
However, without forking the current standard library implementation, this would entail a lot of work, for relatively little gains.

I configured a network balancer for my two instances and the port range of 8080-8080 (tcp:8080). The zone is correct, my instances are in us-central1-f and my network balancer is configured for us-central1.
However, when I try to curl to the network forward rule IP it does not properly route to any of the instances.
The health check on the pool of instances shows that both instances are good. And I can curl to each instances directly.
Am I missing something?
This is old and i don't think I have this issue anymore so I'm just going to attribute this issue to the "ghost in the machine"

Can someone provide some insight why I am getting this error:
"Overload resolution failed because no accessible 'IIf' accepts this number of arguments"
Here is the IIf statement:
=iif(Sum(Fields!CallsRemaining.Value))<0,1,((Sum(Fields!TotalInventory.Value)+Sum(Fields!CallsRemaining.Value))/(Sum(Fields!TotalInventory.Value)))
It only has 2 arguments, so not sure why overloading. Any suggestions would be greatly appreciated.
Thanks.
Parenthesis was in the wrong place. Fixed with simple move:
=iif(Sum(Fields!CallsRemaining.Value)<0,1,((Sum(Fields!TotalInventory.Value)+Sum(Fields!CallsRemaining.Value))/(Sum(Fields!TotalInventory.Value))))

Out of the blue, around 40% of my website's community can no longer visit, saying they're getting "No Data Received" errors. We've taken our firewall offline, tried going through systems such as Cloudflare and checked our .htaccess to no avail.
I've asked affected users to traceroute but the weird thing is it looks like it's being stopped at ISP level.
Can anyone suggest other things that may be causing this error?
