'"Failed - Blocked" messaged popped up when downloading .eml file from servers but it is working locally in localhost:4200

Failed blocked message:

It's an Angular application. when I click the "download" link locally in 4200, the file can download without error. But when downloaded from a rnd server, it pops the "Failed - blocked" error. It is the same Chrome browser I am using in both situations. I see solution of setting "Launching applications and unsafe files." to "Prompted". I checked. The setting was already such. Apparently it is not fixing the "Failed - blocked" error.

Here is the angular code

    this.http.post(this.END_POINT+"/download/" + emailMessageId, Blob).subscribe((res) => {
     
      const byteCharacters = atob(res['something']);
      const byteNumbers = new Array(byteCharacters.length);
      for (let i = 0; i < byteCharacters.length; i++) {
        byteNumbers[i] = byteCharacters.charCodeAt(i);
      }
      const byteArray = new Uint8Array(byteNumbers);
     

      let blob = new Blob([byteArray], { type: "application/eml" });
      var link = document.createElement('a');
      link.href = window.URL.createObjectURL(blob);
      link.download = "email.eml";
      link.click();
      document.body.appendChild(link);         
    })    

  }```

Solution 1:[1]

As far as I know the UID matching the credentials is not exposed in this error message, so you will have to look it up another way. The best I can think of is using the Admin SDK to find the user by their email address.
