Bizarre issue with new wireless router

[smark98]

I just bought a new wireless router a few days ago and have been having a bizarre issue. It's a Tp Link AC1200 Wireless Dual Band Gigabit Router and It works perfectly on my PC but on my phone, it loads all websites except reddit. It just say's "we have some trouble getting to reddit". I've tried from both 2.5Gig and 5Gig bands, I've tried the web browser, a couple of third party android apps and I even manually reset the router and only set up the ISP login and wireless passwords but nothing worked. There's no issues while using the mobile data and I've also factory reset my phone for an unrelated reason and the issue still persists. I've attached the wireless settings from the router.
