F23 problem with mercurial and SSL

[Lester M Petrie]

Hi

Since I have upgraded to Fedora 23, I am unable to communicate with the remote  
mercurial repo that I work from. All the local commands I have tried work fine, 
and I am even able to clone my local repo to another machine, but everytime I 
try to communicate with the base repo, I get the following error message:

abort: error: [SSL: PARSE_TLSEXT] parse tlsext (_ssl.c:590)

I can still communicate with the base repo from a RHEL 6 machine, so it is 
possible to get work done, but it is very clumsy. Does anyone have any 
suggestions of how to correct the error?
