Hi there,
I finally had some time to get an SSL certificate from an official provider. This time I trusted TheSSLMart and bought a RapidSSL certificate. It is affordable, supports most browsers and was relatively easy to install. Now I hope there won’t be any longer issues with accessing the site due to the SSL certificate. After having spent roughly this whole evening on Apache, certificates etc., I’m really prepared to develop something on Meteor again. I’ll get back to that during the next few days, but I think tomorrow I’ll go running again. 😉
