No longer able to open Couchbase Web Console

Running Couchbase Server 5.1.1

Previously we have always been able to access the web interface via https://public-server-name.com:8880/ui/index.html but now am no longer able to publicly access or even curl the address. None of the server configs have changed and the port is still configured for a custom TCP rule in AWS. I am able to SSH into the box and curl the UI via http://localhost:8880/ui/index.html no problem, but for some reason it is no longer accessible publicly.

I have already tried restarting couchbase via sudo service couchbase-server stop/sudo service couchbase-server stop, but to no avail. Previously I have seen this on other machines but just repushing couchbase to the machine would resolve the issue. But since this is production, I’d rather not do that.

Is there a specific, separate service name for the Couchbase Web Console that I can perhaps try kicking?

Any help here would be greatly appreciated.

The Couchbase web UI is on port 8091 by default, so it sounds like you have some non-standard config / port forwarding to map to port 8880.
