Getting resource not found error for Experience fragments

[Abbirami]

While accessing the Experience fragments we are getting 404 Resource at '/content/pagenotfound.html' not found: No resource found . Able to edit the same yesterday.

As far as my knowledge no changes were made.

Please advise what might be causing the issue.

Hi @Abbirami 
Are you getting this error on AEM Author, Publish or when accessing via dispatcher?

If its dispatcher then check filter rules.

- check log and error file 

- Clean dispatcher cache in case of dispatcher 

- check permission / env specific to author/publish?

- if on the publisher, check the replication
