Search error fetch_Fetch.fetchResponse

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):

Describe the issue:
I can’t execute the following request.

(nginx.access.response_code > 400 OR nginx.access.response_code: 301)  AND (nginx.access.url : (*env* OR *git* OR *php* OR *base64* OR "*well-known*" OR *vscode* OR *ftp* OR *phpstorm* OR *admin* OR *setup* OR *wp-content* OR *wordpress* OR *geoserver* OR *webui* OR *hudson*) OR nginx.access.agent : ( *scanner* OR *bot* OR *spider* OR *abuse* OR *proxy*  OR *grab* OR *Fuzz*)) AND NOT nginx.access.url : *email*

I get the following error

I also noticed that some hot nodes of the cluster are loaded by 100%, but not all.
