Macstodon setup

Hi, here.

I guess by now you all have seen the existence of Macstodon - a Mastodon
client in the fediverse for Classic Macs!

It needs a SSL stripping component on another computer in the network,
but that should not spoil the fun.

However, it is not trivial to get it to work properly. I have spent a
few hours now and I just won;t make it to the end ;-)

My system: iMac G3, MacOS 9.2.2 on the Macstodon side
And an Intel NUC with standard Debian 12 and webone 0.17.3 on the SSl
stripping side

Now, the problem is that I can't finish the login sequence. Almost all
steps go OK - although the possibilities of 'logging in' vary a lot with
the browser in use. Netscape Navigator shows beautiful login bozes, but
no button to actually log in. Internet Explorer about the same
experience. Classilla looks OK, but after logging in it does not provide
me with the promised code, but with an error screen.....

So, no luck. I use vanilla webone, so no changes to the original setup.
The Internet configuration on MacOS 9.2.2 is set so the web proxy points
at the webone machine. The web browsers also work with webone - I have
configured their proxy settings.

Anyone?
Regards,
Rene
