Curl: (52) Empty reply from server

I am attempting to install an application on a new install of Nextcloud.
The only modification from the base install so far have been, SSL, theme color, and caching.
I did find other references to other errors in the forum but none of them seemed to address my specific issue.

Error from NextCloud when attempting to install an app

cURL error 35: OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to github-production-release-asset-2e65be.s3.amazonaws.com:443 (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)

Error in Logging

GuzzleHttp\Exception\ConnectException: cURL error 35: OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to github-production-release-asset-2e65be.s3.amazonaws.com:443

Error from curl in bash.

$ curl github.com:443
curl: (52) Empty reply from server

I just found the cause when running curl -v github-production-release-asset-2e65be.s3.amazonaws.com:443
