problem with pushing to github

saw there's a lot going on with iceberg and spec today so likely this is related. Just created (20 mins ago) a new image to push a PR to pharo, and usually in a new image you have to fill in your credentials and you had 'accept' and 'ok' buttons (ok - to accept credentials, accept - to push). Now there's no 'accept' button and it doesn't push my changes anymore. Am i doing something wrong or is this a bug?

P.S. i'm on windows, latest pharo 8.

Best regards,
