APIs not working on mobile (android)
Hi, I made this web app with react and when I call the APIs from chrome on desktop they work perfectly fine.
When I open the web app on chrome android all API requests fail with the following error:
TypeError: Failed to fetch.
Now I know that there are differences between development and production or local and remote
but I don't think these differences extend to simple http calls.
Do you think it might have something to do with CORS?

I am not a code developer.
I don't know if it's a CORS issue.
But if it is, I can just point out others with similar issues.

If you are unable to resolve with this information, I suggest that you post a new topic with Issue CORS in the title, or something like that.
This makes it easier to get help from Travis Bell, the administrator, who has the necessary knowledge and power to solve the problem.

Seems like the problem is not CORS, rather than DNS I guess. When I use VPN everything works. Anyways it's annoying.

In some countries there are problems with Cloudflare DNS service. 1.1.1.1
I don't know which country you are in.
Try changing to Google's. 8.8.8.8
Or any other.

Setting dns to 8.8.8.8 works but I can't make a web app that doesn't work if users don't have the dns set to 8.8.8.8

I'm sorry but I don't know how to help.
Does the problem occur everywhere in the city?
Does it occur with all ISP, Internet Service Providers?
If possible, can you tell me which country you are in?

Albania. I'll try to send the requests from a proxy server, maybe it works
