peach and .Q.hg, conn. OS reports: Protocol not available

peach works with .Q.hg, but I haven’t seen the “Protocol not available” error message before.
Is it possible that IEX doesn’t allow parallel requests from the same computer, or am I doing something wrong.

Hi Anuj,

currently, TLS connections are available for the main thread only.

As a workaround, I found that I could start multiple slave processes (not threads) and the code worked.

Is there a cookbook showing how to keep a SSL connection open and submit multiple GET requests?
