Actual vs expected behavior:

Actual behavior
Sometimes the API response is 200 and sometimes 500

Expected behavior
Every time the API response must be 200

Any other information you'd like to share?

Previously this happened less frequently but now I am getting 500 after every 1 or 2 request

[gladkikhartem]

I have same behavior periodically.
More importantly - I just sometimes receive empty response.
Specifically for requests for translating the text

Same for me with translations. Mostly in ES?
