My instance has been having problems with push federation since
updating to v2.10.2, using the docker image. Posts are not reaching
their destination instance until some other interaction initiates a
fetch from source.
The logs contain lots of errors such as:
```
pleroma | 09:34:40.885 [notice] TLS :client: In state :wait_cert_cr at ssl_handshake.erl:2158 generated CLIENT ALERT: Fatal - Unsupported Certificate
pleroma | - {:key_usage_mismatch,
pleroma | {{:Extension, {2, 5, 29, 15}, true, [:keyCertSign, :cRLSign]},
pleroma | {:Extension, {2, 5, 29, 37}, false, [{1, 3, 6, 1, 5, 5, 7, 3, 1}]}}}
```
This erlang/OTP issue seems to be the same problem:
https://github.com/erlang/otp/issues/9208
The erlang version committed here was selected after discussion in the
merge request.
I have not noticed any federation problems with an image built from
this dockerfile.
