tls fuzz

[pichwo]

sorry, i HAVE a problem with socks as shown below ...

tried everything .... cannot tell whas going wrong with my "existing" letsencrypt cert provided for chisel ...

you write "Setting --tls-domain requires port 443" - i cannot use that port since it is occupied and/or also used by "regular" letsencrypt ... do you use special tags or other magic regarding letsencrypt, so an "existing" cert does not work ???

regards w.p. traces shown below ...
