This is my hosting company’s response:
Unfortunately, we are not seeing any evidence of this being blocked. We are able to reproduce this issue but we are not seeing any errors displayed or logged in regards to this being blocked in the firewall or ModSecurity rules from today or our tests. We even temporarily stopped the firewall entirely to test and it still had the same issue.
We are able to curl the api gateway domain without issues from the command line as well. Which indicates this is some kinda issue on the remote end most likely.

We also disabled all the plugins temporarily to test and also tested with WordPress default rules and this also had no effect.
Seems like other people have had this problem before we recommend reaching out to them and having them investigate. Once they let us know what this error means and how it’s being blocked we can look further.
