Very weird. I had everything working just fine yesterday. My initial problem was actually that it was timing out, but I was able to fix that with a few things…
- Adding a rule in windows defender firewall to always allow on local port 19000.
- Making sure the network I was on was “private” as in it was able to be detected.
- Gave the expo app permission to draw over other apps.
After doing all those things I was able to get it working just fine yesterday for several hours and several refreshes. I tried again this morning and I got the error mentioned in the title.
