"Temporarily unreachable" when using fetch as Googlebot from Webmasters Tools
According to Google, it's because:
- Fetch as Google can't currently fetch your URL because the server took too long to reply.
- Or Fetch as Google cancelled your fetch because too many consecutive requests were made to the server for different URLs.
I've witnessed this happening a few times in the past. More often than not, it's an intermittent problem that goes away after a short period of time.
Note the URL is not unreachable for all of Google - It is just unreachable for the Fetch as Google simulation tool.
Old thread but I had this issue, it was due to making changes on cloudflare supported TLS version. Google does not support tls 1.3 yet - make sure your servers allows tls 1.2
