Hi,

I am trying to securely connect to my Rstudio server via https located at [https://srv1.stats-con.com:8787](https://srv1.stats-con.com:8787), however, I get this error on Firefox: Secure Connection Failed Error code: SSL\_ERROR\_RX\_RECORD\_TOO\_LONG

Connection via [http://srv1.stats-con.com:8787](http://srv1.stats-con.com:8787) works connecting to Rstudio (unsecure). Connection via [https://srv1.stats-con.com](https://srv1.stats-con.com) works, too, connecting to OPAL server (secure).

How do I have to configure my RStudio, NGINX, certificates (certbot, Lets encrypt)?

Best, Wilmar

`https` is configured for port 443. You should have a different subdomain (than `srv1`) for rstudio (like [rstudio.stats-con.com](http://rstudio.stats-con.com)) and a specific nginx config + let’s encrypt certificate as well.

Thanks!

1. I registered a new Typ A record of an domain address with a provider
2. I created a certificate with certbot:

> sudo certbot --nginx --cert-name [stats-con.com](http://stats-con.com) -d [srv1.stats-con.com](http://srv1.stats-con.com) -d [rstudio1.stats-con.com](http://rstudio1.stats-con.com)

1. I added a reverse proxy pointing to port 8787 in /etc/nginx/sites-available/default:

> location / {  
> proxy\_pass [http://127.0.0.1:8787/](http://127.0.0.1:8787/);  
> proxy\_set\_header Host $host;  
> }

Works! 🙂
