@m-mohr To be clear, this is an error that you're seeing today? We had an issue with multipart uploads (which your file would be using) but pushed a fix earlier this week: source-cooperative/data.source.coop#180

[alukach]

Upon further review, your issue wouldn't be impacted by source-cooperative/data.source.coop#180 (that was an issue with special characters in the key).

I'm unable to reproduce this. Perhaps more information would help:

• Did any part of the upload complete? (check your browser's network tools)
• What product are you uploading to?

[alukach]

Sifting through the logs for PUT /ftw/global-data/predictions/vectors/alpha/2025_with_confidence.pmtiles requests, I can see that we had 72 200 responses and 1 520 response. I admittedly don't know why that signature mismatch happened. While this is not a satisfying answer, I do think that occasionally random failures can occur (eg clock drift, dropped bytes on the network, etc) and a request fails. I believe that #425 (not yet deployed to production) may help with these situations. I'm going to close this for now but recommend we re-open if these errors continue to arise.

[alukach]

Actually, closing this comes across as more dismissive than I meant it to be. Let's keep this open and keep an eye on it.

@m-mohr I'm curious to hear if you tried the "retry" button and if the error repeated itself. Are you unable to upload through the browser today?

[m-mohr]

Retry repeated the issue. I also tried a differently browser, but the same file. I only tried this file recently, Im wondering whether another file would work, but am not at my work computer right now. I was avle to upload another file some weeks ago.
