Cannot connect to my server

[eightcastles]

Hello, something changed over the past week or so. I can connect locally to my server, either on my phone via wifi or my PC over wifi. As soon as I leave wifi and try to connect like I always have, I cannot reach my server. I can however reach the demo, so i know my phone is working. I have looked at all my security settings but cannot figure out. Can someone help me start troubleshooting? TY

Your ISP likely changed your public WAN IP address. Are you using the vanity url to access, and via web or app? Try going to settings->Network and click SAVE button at the bottom, and retry.
