Can't contact support. No community instance for development.

When I tried the support page on the community site here, I clicked this button:

it took me here: https://forum.appian.com/suite/sites/myappian
and then it forwarded me here: https://forum.appian.com/suite/saml/AssertionConsumer
and then all it said was "401 - Unauthorized".


I wanted to ask about this because I'm having the same problem as this: https://community.appian.com/discussions/f/general/23264/community-instance-gone

I can't find my community instance and there is no button or panel to create or reset one anymore, my "instance" is just gone entirely.

I haven't logged in in a while and it was very confusing to understand how to proceed with the tutorials without an instance to use...

Could someone please fix the support page? Could someone please fix my community instance?

Thank you,

A
