XF 2.3 Bounce email setup - Oops! We ran into some problems

[nodle]

I keep getting this message, and can't seem to figure it out. I have created a bounce@mydomain.com email and added and saved it to the bounce email address. Then I got to Setup>Options>Email options>Automated bounced email handler and clicked on Enable. It brings up some selections, and I have tried both IMAP and POP3, but when I punch in my info, this is the message I get. When I close out of the window, I have no server error messages either. I have tried this using either the Xenforo PHP sending method or the SMTP sending method for the mail delivery system, and both produce the same results. I have checked my credentials and have even deleted/recreated the mailbox. I have tried both on my home computer and office computer with the same results. Any ideas?




Looking at the console, it says: /admin.php?options/emailBounceHandler/email-handler-server:1 Failed to load resource: the server responded with a status of 403

That’s the problem. Find out why you are getting a 403 (ModSecurity? Cloudflare? You should be able to get more info by inspecting the response in network tab) and fix that.

It doesn't really tell me all that much, just ends at fetch.

Click the entry and inspect the response

It's just blank, tried it twice.

Your last screenshot somewhat hints that you are using Cloudflare.

If this is the case:
Check the response headers, get the Ray ID and check Cloudflare logs.
