<h1>Authorization Required</h1><p>Please check whether the MAILMAN_ARCHIVER_KEY is provided by you and it is correct.
Find MAILMAN_ARCHIVER_KEY in settings.py and mailman-hyperkitty.cfg, and make sure they are the same and have correct syntax (settings.py is a Python source file and the value must be surrounded by matching quotation marks, while mailman-hyperkitty.cfg is a .ini-like file and values must not have quotation marks).
Please do more work at your end. I'm tired of doing your work for you, with you functioning as a very slow remote terminal. We've got good documentation as software documentation goes. Read it. In this message, you typed "help me" right under the key lines quoted above. If you won't read the log and try to find something you can understand, why should we do it for you? At the very least, when the error message says "Please check this variable", you should be able to do "grep this_variable /etc/mailman3/*" to find which files contain settings for it.
