I hit this again shortly before:
Wed Jan  1 18:29:48 UTC 2020
while accessing:
https://www.postgresql.org/message-id/resend/CAMkU=1zBJNVo2DGYBgLJqpu8fyjCE_ys%20msr6pOEoiwA7y5jrA@mail.gmail.com
"Not Found - The requested page was not found."

The previous page in my history was:
https://www.postgresql.org/message-id/CAMkU%3D1zBJNVo2DGYBgLJqpu8fyjCE_ys%2Bmsr6pOEoiwA7y5jrA%40mail.gmail.com

So I guess the issue is with %3D (=).

And for no apparent reason, when I go "Back" and reclick "Resend email", then
it works, now with URL:
