Particularly Firefox on Debian testing/9 is affected: it gives a blank page without any error messages.

We suspect the issue is:
Server negotiated HTTP/2 with blacklisted suite
RSA 2048 (SHA256)   |  TLS 1.2  |  TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA  |  ECDH secp256r1

The webserver is updated and the cipher settings modernized. It works for me across multiple browsers so I'm marking resolved. Please reopen if the problem persists for you.
