My NGINX configure redirect for HTTP to HTTPS.
That all looks fine to me. The error below is a TLS authentication error:
HTTP Error 400: HTTPSConnectionPool(host='localhost', port=443): Max retries exceeded with url: /postorius/api/templates/list/list-id/list:user:action:subscribe (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1029)')))
Which log did you find this in (nginx or uwsgi)? It says it couldn't verify a certificate, which suggests to me that that the httpd's database of CA certificates is incomplete.
