"Current IP is restricted, please use a proxy" "Dubbing error count exceeds 1/3"

Errors like those above generally appear during the dubbing stage when using the "edgeTTS" channel. This is Microsoft's TTS service API for the Edge browser's "Read Aloud" feature, available for free. Recently, new rate-limiting measures seem to have been implemented, where too many requests from the same IP in a short period can trigger a 403 block, leading to errors.

How to Resolve?

First: Check if there is a latest version patch. If available, download and overwrite to upgrade, then test if the issue is resolved.

Second: If you know what a proxy/VPN/wall is, use it by entering the HTTP proxy address into the "Network Proxy" text box.

Third: As shown below, click on "Dubbing Channel," and in the pop-up window, set the concurrency to 1 and the pause to 5. This reduces errors by slowing down the dubbing speed.

Fourth: If the above methods do not resolve the issue, try switching to another dubbing channel.

For example, free dubbing services include "GPT-SoVITS," "ChatTTS," "F5-TTS," "CosyVoice," etc. Deploy these projects locally, and the settings dialog will provide corresponding tutorial links.

Alternatively, use paid online APIs such as 302.AI, ByteDance Volcano Voice Synthesis, OpenAI-TTS, etc.
