Wow, Chameleon worked perfectly!! I put ticketmaster.com in the whitelist, profile with Chrome, and boom, it loaded. I tried re-enabling uBlockOrigin and Privacy Badger and still works.
Troubleshooting mode didn’t work so it’s very weird, I don’t know what kind of checks this website is making. Anyways thanks for the help!
Thanks for the pointers!
For now, changing the user-agent as suggested in another comment did the trick. Later I will try to debug with your steps and see if I can track down the root cause.
