Hi.
I'm having a strange issue when proxying a self hosted Sentry [1][2] instance. It works when accessed directly (to the Docker port), but throws Javascript error in console when proxied via nginx.

It doesn't appear an application problem, because as I said it works fine when accessed directly. I raised an issue to Sentry [3], but it appears something related to the proxy.

I tried different browsers and in incognito mode, same behavior.
I failed to find where the problem could be. Any hint is welcome.

Thanks


In JS console I see:
