ESPN Playback - Connection Errors

Within the last week, my ESPN app has randomly stopped working. When I try to play a live stream, I get the following error:

"Connection Error - We are unable to connect you to the service. Please verify that you are connected to the internet and try again". 

Despite what this message seems to imply, my internet (and subsequent tv's connection to said internet) are both working like normal. I'm using an Orbi AX6000 mesh router setup with gigabit internet through Spectrum, which has been working perfectly with my TVs up until this issue started happening. All other applications on the tv work like normal and I can stream from these other apps with no issues whatsoever. I have tried the following troubleshooting steps:

1) Tried both WiFi and ethernet connections. Minimum connection speed was ~500 mbps download. No change in performance.

2) Tried the ESPN app on my phone and the ESPN website on my laptop, both of which work fine.

3) Ensured there are no current reported issues with my ISP in regards to streaming ESPN or other streaming services.

4) Verified the firmware status on my router, TV, and application. Interestingly, none of them have any record of a firmware update in the time span in which the issue started occurring.

I reached out to ESPN's tech support but have not gotten a response, so I thought I would try here to see if anyone has dealt with the same issue.
