When translating original subtitles into target language subtitles, a connection is made to the translation API service. If it fails, it will retry, but if it still fails after retrying 2 times, an error will be reported.

Currently, a total of 11 translation channels are supported, but almost none are directly available for free.

1. Although there is a free trial, there are frequency limits and character limits (such as Baidu Translate and Tencent Translate). When the frequency limit or character limit is reached, it will naturally report an error and become unusable.

2. Scientific internet access is required for free use, such as Google Translate and the occasionally erratic Microsoft Translate. If a proxy is not used or the proxy is unstable, a connection failure error will definitely occur.

3. DeepLX, which uses DeepL for free, needs to be deployed locally, and the IP is blocked after a few uses, leading to errors.

4. If you want to use the paid version of DeepL, you need to confirm that the authorization key is correct, otherwise an authorization error will be reported.

5. Using the official ChatGPT API interface, free users are only allowed 3 requests per minute. If there are more, an error will be reported. If you are not a paid user, do not consider the official ChatGPT, as it is impossible to use it. Even with a paid account, scientific internet access is required.

6. Using a third-party relay ChatGPT API interface, the API address provided by the third party may also be blocked. Without a proxy, a connection cannot still be made, naturally reporting an error.

7. Kimi, Qwen, and many other large models provide fully compatible OpenAI interfaces, which can be regarded as third-party ChatGPT API use. Just fill in the relevant API address and SK in the ChatGPT API settings.

In summary, each translation channel has requirements for proxies, APIs, keys, etc. If these requirements are not met, an error will definitely be reported.

If an error occurs, carefully check the API address, authorization key, proxy, etc. for the translation channel you are using and troubleshoot them one by one.

Finally, to help novice users get started quickly and avoid getting stuck in the translation channel, the "FreeGoogle" translation channel has been specially added after version 1.40, which does not require a proxy or any configuration. Just select it to use it.

If you are not a novice, please do not use this translation channel. There is a request limit, and an error will still be reported if it is exceeded. Please leave room for requests for novice users. This channel is essentially a reverse proxy of Google Translate.
