403 doing any sort of post sending events


I have a Sentry server that was happily logging events. However, that server was left idle for a while and now refuses to accept any logging events.

It’s a docker install with an nginx proxy and seemed to be running perfectly. I’m accessing it mainly by a C# client but have changed the code slightly. While this might have been a concern, I’ve also tried the JavaScript and C# examples verbatim from the project integration page.

In each case the server responds with a 403, whether I go via the dns entry, or via IP address and port 9000.

Does anyone have suggestions on how to debug this?
