Background of the issue:
I am trying to duplicate products to a new language using 10/25 product batches. You can see the issue on this page: 隐藏链接.
Symptoms:
I expected everything to be duplicated, but instead, I got an error: 'Sending for translation failed. There was a problem sending your content for translation. Please try again in a few minutes. If the issue persists, please contact our support.' Additionally, there is a 520 error indicating 'Web server is returning an unknown error'.
Questions:
Why is the translation process failing?
How can I resolve the 520 error on my website?
