Can't browse GraphQL documentation when logged in via https

In my 15 test system using letsencrypt certificates, if I login into FreePBX via http, I can browse GraphQL Documentation tab with no issues. If I then login using https, and browse the same tab, the request fails with the below error. Similar community report here on FreePBX 16:
