 Welcome!

 Regarding your connection issue, try opening this URL in a browser and see
 what happens
 <https://ywg.ca.packages.macports.org/mirror/macports/packages/libgcc7/>

 If that works fine, try downloading a file from that url with curl and see
 what what happens
 {{{
 curl -O
 https://ywg.ca.packages.macports.org/mirror/macports/packages/libgcc7/libgcc7-7.5.0_0.darwin_19.x86_64.tbz2
 }}}

 The full details on how to debug this are here
 <https://trac.macports.org/wiki/MisbehavingServers>.

 FYI -- gcc7/libgcc7 is quite old, and may not work / be able to be made to
 work on BigSur.

 The current gcc flavour for you would be gcc10 -- will that work for you?
 {{{
 sudo port -v install gcc10
 }}}
