Loading mtc.js and forms scripts failed

Your software
My Mautic version is: 3.1.2
My PHP version is: 7.3
My Database type and version is: MySQL 5.5 (What Bitnami had set in the .php files, though I still had to set server_db_version in config and local.php to 5.7 for Mautic to work properly)

Your problem
My problem is:

My tracking script won’t load. And my embedded forms are not loading half of the time.

These errors are showing in the browser log:

Loading failed for the with source “https://BitnamiEC2IP/form/generate.js?id=1”.

Loading failed for the with source “https://BitnamiEC2IP/mtc.js”. home:1:1

Loading failed for the with source “https://amautic.mydomain.com/mtc.js”.

GTmetrix shows “No Response Headers - Request failed” as the reason for failed loading.

These errors are showing in Mautic logs:

Steps I have tried to fix the problem:
Read every relevant DuckDuckGo and forums post I could find.
I’ve modified the tracking script with a whole variety of URLs including straight to my Bitnami AZ EC2 IP, a subdomain on my domain that routes to that IP, etc.
Installed SSL certs on Bitnami instance for amautic.mydomain.com domain
Maybe more, it’s been a few hours now

Any ideas?

EDIT: Well, my dumb ass had uBlock Origin on and was blocking the scripts myself… Not sure how the forms will fare. They’ve been finicky.
