Description
We updated to Jenkins LTS 2.249.1 and also updated the EC2 plugin to 1.52.
After performing the update our existing EC2 key pair credentials were lost. It appears that the plugin is now supporting the Jenkins Credentials plugin.
When we attempted to set the credentials within the Configure Clouds UI, we'd see an error saying that this API required a POST. There was a button to provide the POST request. However, this did not actually save the credentials.
We have downgraded back to 1.50.3 to be able to continue to get EC2 slaves running again.

using the latest version (1.53++) I can't seem to reproduce this error.
I started a new instance set the credentials, saved and went back to the manage page and changed the credentials with no issue

Same here, but I managed to work around it. Basically, ignore the "POST required" error.
I added the SSH key through Manage Jenkins -> Manage Credentials, then I selected that key in EC2 plugin. It complained about POST, but I just ignored it. Did the same for all "clouds", then saved. It works now.
Also, the checkbox to use IAM instance credentials was unchecked, which is why it was failing to launch new instances in my case.
