Launch Initiation Failed: Trying to launch EC2 instance on eu-north-1-hel-1a

Hello,

I am trying to launch a dual-stack EC2 instance on a specific availability zone (eu-north-1-hel-1a), but the process seems to be failing at the last step. I have even tried to drop the dual-stack requirement and limit myself to ipv4 but this didn't seem to do the trick. The original message is as follows: Instance launch failed: The requested configuration is currently not supported. Please check the documentation for supported configurations.

Has anyone else faced this issue in the particular availability zone? I am trying to figure out what is not really supported and whether I could get around it.

Many thanks in advance.
