When I try to authorized Steam to sign in to api.faforever.com, I get this error:
{"requestId":"5ccea8d7-f4b8-4858-9deb-d11c29e3cac9","errors":[{"status":"500","title":"org.springframework.web.client.HttpClientErrorException$TooManyRequests","detail":"429 Too Many Requests: [<html>\n<head>\n<title>429 Too Many Requests</title>\n</head>\n<body>\n<h1>Too Many Requests</h1>\n</body>\n</html>]"}]}
I retried now and it worked.
