Jekyll Webrick Error

I’m getting the following log in my console when building website project locally:

[2020-01-29 15:34:01] ERROR Errno::ECONNRESET: Connection reset by peer @ io_fillbuf - fd:16

I suspect that’s the reason why the styling in the website doesnt look quite ok. I get images messed up, hover effects does not work, and so one.
It is important to hightlight that this is a static web page that is using SiteLeaf as CMS and being deployed with AWS.

I’m not quite handy with Ruby, neither Jekyll… I would highly appreciate your help.
