Docs review summary
Focus areas
- Style and clarity: One future-tense issue on the new sentence at line 85 ("will log" → "logs"). The new API error block and paragraph additions read clearly.
- Jargon:
MasterNotDiscoveredExceptionandmaster_not_discovered_exceptionare used correctly in inline code/code blocks; the link to master-eligible nodes provides helpful context. - Frontmatter and applies_to: Pre-existing; no changes introduced by this PR.
- Content type fit: Troubleshooting page. The new content (error payload example + log identifiers) fits the resolution pattern well.
- Parent issue satisfaction: No linked issue. The PR's stated goal — making the master-not-discovered error searchable — is satisfied by the additions.
Notes
- Vale found no findings for the eligible files. One manual style finding (future tense) is noted above.

Cheers, @yetanothertw! Ready again 🙏 . FWIW for grammar-not-technical edits, you're welcome to directly edit not just suggest 🙂 |

Summary
👋 howdy! This is one of the most common ES cluster formation/API errors online, but not currently searchable in our docs. So just adds the log & API forms of it. TIA!
