Network Failure on SES Identities Web Interface


I am receiving a Network Failure error when trying to access SES Identities via the AWS web interface. The following URL gives me the network error:

Based on the console log, it appears to be a CORS error. Here is an error message from the console log:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at (Reason: CORS request did not succeed). Status code: (null).

I have tried multiple browsers (Firefox, Chrome and Safari). I have cleared my cookies and cache. I have even tried disabling CORS with a browser plugin. Nothing works. I am able to access Identities in us-east-2, so the problem seems unique to us-east-1.

However, I need to be able to work with SES in us-east-1 because that is where our account is set up.

AWS Support told me that some customers connecting through a certain ISP are experiencing this issue. AWS Support's recommended solution is to go into your router's firewall settings to allowlist the endpoint "".

I solved this by connecting to the internet through a VPN, and thereby bypassing any firewalls used by my ISP.

It is displayed without any problem in my environment.
Does the same error occur even if you connect from another network or from another PC?
