Steps to replicate the issue (include links if applicable):
What happens?:
Instead of a preview, we get a yellow box saying "Reached max retries. Try again later. Retry" and when I click on retry, it sometimes gets the same message, or "Wikifunctions returned a failed response: Error in evaluation"
What should have happened instead?:
It should show a preview of the text.
Software version (on Special:Version page; skip for WMF-hosted wikis like Wikipedia):
