[Pkg-matrix-maintainers] Bug#1025385: nheko would crash if home server does not have a .well-known served

[Boris Shtrasman]

Package: nheko
Version: 0.8.0+really0.7.2-4
Severity: normal
X-Debbugs-Cc: borissh1983+bugs at gmail.com

Dear Maintainer,

I was connecting to an in-house matrix-synapse server,
  the server was setup behind a revese proxy (apache2) but did not have a .well-known served,
  the server did not have an SRV record declared.

I entered @user:subdomain.example.com , and nheko ... crashed.

Example:

[2022-12-03 20:22:28.132] [qml] [warning] QVariant::load: unable to load type 1025. (:0, )

I expected nheko to try to connect to fallback to https://subdomain.example.com as the matrix server.

Having a well-known folder with server that return the same values work as a workaround:

cat /var/www/html/.well-known/matrix/server 
{ "m.server": "subdomain.example.com:443" }
