09/11/2026, 10:07 AMHTTP -1 error means that your script isn’t receiving a response at all. Based on our logs, the requests are being blocked before they reach our API. Your proxy is refusing the connection to <http://api.reply.io|api.reply.io> with a 403 at the tunnel stage, before the API key is even sent.
Could you please ask the administrator of your cloud sandbox to add <http://api.reply.io|api.reply.io> to the egress allowlist, or run the script in an environment with normal internet access?
Also, we can see that all API calls from your account stopped at around the same time, including sequence and contact requests. If these calls are running from the same sandbox, fixing the allowlist should restore them. If they are running elsewhere, we recommend checking what changed in your environment on the evening of September 10.Hessan Haiderzada
