Been running pikapods for about a month for FreshRSS and just today it stopped working. After some troubleshooting, it looks like xfinity/Comcast is flagging pikapods as a risk through their “Advanced Security” feature through their hardware. The only way I could permanently get through it was to disable the advanced security setting. Just FYI if anyone has similar issues.

Edit: its just the configured pod address to the FreshRSS server that was inaccessible. The main pikapods.net site was still accessible. This is with valid SSL certificates, and on multiple devices, and only on the WiFi network that I use. It was completely accessible via mobile network.
