I have a very strange issue with several sites hosted on one of my servers. They are Wordpress sites created with easyengine and using letsencrypt (–wpredis --php7 --le).
On Desktop everything is working normally, but since last letsencrypt renew i think (for all of them) on mobile they get a:
The site can’t provide a secure connection. ERR SSL PROTOCOL ERROR
Even more strange, on my phone they work on WIFI but not on 4G. I tested them on ssllabs and they get a B grade and a: Warning: Inconsistent server configuration
But sslshopper tells me everything is ok.
