Mint.HTTP.connect can throw CaseClauseError

[sezaru]

Sometimes I get CaseClauseError during Mint.HTTP.connect call.

The error occurs in lib/min/negotiate.ex line 113 because transport.negotiated_protocol(socket) returns {:error, %Mint.TransportError{reason: :closed}}.

This is the error I got:

{:error,
     %Honeydew.Crash{
       reason: %CaseClauseError{term: {:error, %Mint.TransportError{reason: :closed}}},
       stacktrace: [
