Hi,

The issue is that your site is serving only HTTP/3. Some of our tools don't work with that experimental protocol yet.

I see you're serving your site from Cloudflare. You can turn off HTTP/3 by logging into Cloudflare -> Network -> Http/3:

Try turning that off, at least while you run PWABuilder. It should work for you after that.

Hello Judah, Thanks for your reply

yes i am using cloudflare and I turned off http/3 from cloudflare and tried to build app, and i am sorry i still getting that manifest.json.Responded with status 503 error.

any idea for solution ?

Please share if any..
Thank you in advance.

Hmm, I am seeing the same, even though I see Cloudflare serving your site as HTTP/2.

Can you try disabling HTTP/2 in Cloudflare and packaging with PWABuilder?

Again, this would only be temporary to create the package. You can turn these back on after creating the package.

[JudahGabriel]

Technical background: PWABuilder's Android platform uses node-fetch, which doesn't yet support HTTP/2 ☹

Once node-fetch supports it, PWABuilder Android platform should start working fine on sites that support HTTP/2.

@yashhooda Can you try disabling HTTP/2 and HTTP/3? I suspect that will fix your issue. After you generate the package, you can turn these back on.

Hi Sorry, just disabling HTTP/3 does nothing and there is no way to disable HTTP/2 but disabling cloudflare works , i'v done that and got the package without any issue.
I want to thank you for your time and support an good luck for pwabuiler
Thank you
