Manual approval for an addon/theme won't work

[ioanarusiczki]

STR:

1. With an admin account load AMO dev or AMO stage and try to approve an add-on or a static theme https://reviewers.addons.allizom.org/en-US/reviewers/review/name45

Expected result: The addon/theme is approved.

Actual result: A 504 Gateway Time-out is displayed.

Notes: I could reproduce the issue on AMO dev and AMO stage with FF76(win10). The issue is not reproducible for the Reject button.

Same on stage https://sentry.prod.mozaws.net/operations/olympia-stage/issues/8481644/?query=is%3Aunresolved

@ioanarusiczki We believe the problem has been fixed on the Autograph side. Can you please try again?

[ioanarusiczki]

@diox It is still reproducible right now on dev and stage.

[smarnach]

@ioanarusiczki Thanks for checking! Autograph ops found another problem. We will let you know once it is fixed.

[smarnach]

@ioanarusiczki Ops made another change. Could you please try again?

[ioanarusiczki]

@smarnach Same result I'm afraid. 504 Gateway Time-out

[smarnach]

@ioanarusiczki Thanks again, and sorry for the trouble! We'll try to figure out what's going on.

[ioanarusiczki]

@smarnach I'm updating: seems to be working now on both testing servers.

[smarnach]

Great to hear, and thanks for your patience!
