Your assumption is correct. I did not use the back button. I went to https://localhost/mailman3 the clicked on the signin button in the upper right. After filling in the username and password the 403 page came up.
If it matters, I tried the "forgot password" link and it immediately went to the 403 page. I tried with both Firefox (my main browser) and chrome.
