bonus.SSL_for_RTL.sh made nginx fail to run

[grnqrtr]

I used your script to enable SSL for RTL, but it made nginx fail to run.

admin@GRNQRTR:~ $ sudo systemctl status nginx

I checked /etc/nginx/nginx.conf but couldn't figure out what needed to be changed to get it working so I ended up commenting out the whole "SSL for RTL" section and now nginx is running fine. Here's my /etc/nginx/nginx.conf:

}

BTW, I've used your other scripts to install BTCPay Server and Electrs. Is there conflict with that?

Thanks for reporting.

Yes it is in conflict with BTCPay.

Change the line:
ssl_session_cache shared:SSL:1m

to

ssl_session_cache shared:SSL-RTL:1m

and it should work.

Will update.

Also consider editing out your dynamicDNS from the post to avoid sharing your IP.

Dang, your fast :)

Everything is working fine now, thanks!
