Blank (white) screen on (any) language selection - Galaxy S23 - One UI 5.1 Android 13 #73

Open markjohngraham opened 1 year ago

When I select any language I get a blank (white) screen.

Or (sometimes) I get "If this screen does not load, check your internet connection or try updating or re-installing the language transfer app."

Have re-installed 3 times.

This is on a new Galaxy S23 - One UI 5.1 Android 13

Thanks for reporting! I'm not sure what's going on here, but I'll be on the lookout for patterns.

Are you able to access this link in your phone's web browser?

https://downloads.languagetransfer.org/spanish/spanish-meta.json

(in the worst case, by the way, the files are also available for offline download if you can't get the app working: https://www.languagetransfer.org/free-courses-1)

Apologies for the trouble!

No... error connection refused.

Thanks!

Redirects to:

And I can not connect to that URL

Interesting!

Is there any chance you have something at your network level rerouting requests to .dev domains? Maybe an internal DNS server or a VPN? I know those used to be more common as mock hosts for development (before .dev became an actual gTLD), but that subdomain of r2.dev (controlled by Cloudflare) is the true address of the CDN bucket.

Yes, very interesting… after doing some more testing.

Comcast (major US ISP) seems to be blocking access to that URL.

I am able to access via Verizon.

Hmmm...

I think I've identified and fixed the problem! Can you give it another go for me?

Thanks!

(it turns out the r2.dev domain is rate-limited, which is unfortunately a change Cloudflare made after I set everything up, and then didn't tell me about...)
