Users are saying they cant access the website at all, with the error ERR_FAILED - website is either unavailable or moved permanently. The reason why i think its a Cloudflare issue is because the auto generated firebase url (which doesnt go through the Cloudflare system) works for them (https://monkey-type.firebaseapp.com/). Please help
So, the DNS record is proxied and both existing and pointing to the IP of Firebase hosting?
Nevertheless, both non-www and www domain name are being added to your Firebase project → Hosting and configured/allowed to redirect non-www to www (or vice-versa?) when adding custom domain to your Firebase project?
May I ask, at the SSL/TLS tab of Cloudflare dashboard, have you got Flexible, Full or Full (Strict) SSL option selected?
Furthermore, my Cache Level is set to Standard and Browser Cache TTL set to Respect Existing Headers - in case if you have made some changes and got cached a bit. Not exactly related to the error you posted in your first post (Screenshot), but …
The biggest issue is that this only started showing up about last week. Before it was working fine.
EDIT Another weird thing is that switching browsers for some users helped, AND some users are reporting that its working on their phones (thats on the same network as the main machine that is having issues)
Some of my users are reporting the same problem as above. They see the ERR_HTTP2_PROTOCOL_ERROR on desktop PCs. It works for some, but not for others. It always seems to work on mobile. Everything was fine until 2 days ago. Any advice?
EDIT: I cleared the CF cache. I think that helped in my case.
