Hi @david , sorry for late reply.
Yes the site is accessible (redirects to Bots: An introduction for developers ).
Also getting this below error.

@codinghorror Recently openssl version was changed in latest discourse docker container due to which this issue is arising. On host machine I tried using OpenSSL 1.1.1 for telegram api and it loads the certificate.
